Use a rod coupler
Since your title specifies low cost you can save some money by using a wired lav mic like this Audio Technica or this Olympus lav mic. You simply plug it into the camera's mic input. A 3.5mm extension cable might be needed to reach the camera. Use the lav mic with an inexpensive voice recorder if you need the subject to move around. Smart phones have decent audio recording apps too. Syncing the audio in post can be a hassel so only do this if the shot requires being untethered. If you record audio with a separate recorder it helps to mark it by saying a scene number and making a clap sound so you can find it and sync it with the video editing software.
For lighting you might consider an inexpensive LED light and a second battery. Charge one battery while using the other.
I've used clamps like this and this for quick and simple mount of camera and small lights to a chair, windowsill, cupboard, etc. You can use JB Weld to put a 1/4-20 nut-coupler on the light if it doesn't have it already.
edit: I like Canon equipment and their line of Vixia Camcorders starts at around $300 and has a mic input. The lens and image stabilization gets you a nice picture compared to a camera phone or similar "cheap" camera.
IIRC Premiere has a basic mode that uses a simpler timeline more like Apple's iMovie. You can download 30 day trial versions of the latest Adobe products. Give Premiere Elements a try.
I got a long piece of all thread that matched the same thread as the Clicgear wheels I bought for it. Drilled out the holes where the bottom roller blade wheels are so the allthread could fit through snug. Then used female to female nut union/coupling to fasten the Clicgear wheels to the allthread. Here's about what I used. Cost ~$80 to do, so I'd make sure you get the right stuff as this was a quick google. You could call Clicgear and ask them all the thread size info and go to grainger and make sure you order the right nut/allthread. You could also go on Zuca Mods on facebook and ask there. Very active community.

I made something similar using the MFJ 1979 20M 1/4 wave vertical, something like a Hustler mast or MFJ-1600T mast extender, and a Wolf River Coil.
You'll also need 3/8 x 24 coupling nuts
and some way to mount the mast like one of these: Mirror Mount.
Here is an early version of my backyard HOA stealthy 10M-80M vertical telescoping antenna. It works pretty well. https://www.youtube.com/watch?v=4W5FFX3movg&t=9s
Coupling Nut?

Are they being used to hold two bolts/threaded rods together?
You could use a short 1/4"-20 coupler (example linked) combined with a 1/4"-20 male to male adapter. Also worth looking at the hardware store since 1/4"-20 is very common.
>Foil pommel nut inside

>Foil pommel nut outside
The inside-hex nut on my epee is 22mm (0.866 inches, or just under 7/8 inches) long, has an outside diameter of 10mm (0.394 inches, or just over 3/8 inches), and is sized for a 6mm (0.236 inches, or just under 1/4 inches) hex key. Approximately the top 5mm are not threaded, leaving approximately 17mm of threading.
Most fencing tangs are threaded using 6mmx1mm threading (source 1, source 2, source 3).
It seems like the inside-hex hut would be an example of an "Allen nut"/"socket nut", which McMaster-Carr apparently does not carry in metric specifications.
Though, these, these, and these look like they would be able to serve as replacement outside-hex nuts.
>Foil pommel lock washer
The "split lock washer" would have the same OD as the nut (that is, 10mm, or just over 3/8 inches) and an ID equal to or greater than the OD of the threading (that is, 6mm, or just under 1/4 inches). You can probably find matching split lock washers at your local hardware store without too much difficulty.
>Foil insulation tubing
As others have suggested, heat-shrink tubing from McMaster-Carr with a 3mm (0.118 inches, or just under 1/8 inches) diameter should work.
>Foil german point spring
You'll have to measure several aspects of the springs in question - specifically: the diameter/gauge of the wire that makes up the spring, the outer diameter of the spring (that is, the outer diameter of the cylinder represented by the spring), the uncompressed length of the spring (that is, the height of the cylinder represented by the spring), and the number of coils in the spring - to find a match; see here and here.
The point spring, and the other components not already discussed, are probably more-easily sourced from a fencing equipment supplier than trying to find the same components elsewhere.
