Okay so. Here's what I'm thinking. I only saw the picture you posted, so it looks like you have 1,000 square feet or less, yes? That makes it kinda easy.

First we'll need to know which zone you're in. That will help pick your grass type. It looks like you have cool season grasses, which means you'll be choosing among various fescues, Kentucky bluegrass, perennial ryegrass, etc. That's kind of up to you. Do a little googling and see what you come up with.

Second, you have a lot of weeds in there. It looks like you have either poa annua (annual bluegrass) or poa trivialis (Hell on Earth), or possibly both mixed in there. Those are seriously not good. Not only do you have a lot of weeds, it looks like you might have a significant mix of grass types, and I'm not positive that it's worth saving. Here's what I would do. Keep in mind that this might be overkill for you.

From now until July:

• Get a soil test. Your local agricultural or state university will probably have a soil test program. This will help you figure out how best to treat your soil with fertilizer when it comes time to grow real grass. (~$30)
  
• Kill off basic broadleaf weeds with a 2,4-D product before they can drop seeds and make next year worse. This one is probably one of the easiest. Your choice. (~$10)
  
• If you're feeling like you want to care for your soil, throw down some Milorganite. Not exactly necessary at this time cause we don't know what your soil test will come back with. (~$14)
  
  Sometime in July:
  
  
• Spray a glyphosate product to kill everything. I use this one, but you can also use RoundUp from any hardware or big box store. The active ingredient is the same. (~$30)
  
• It will take ~2 weeks to see results from the glyphosate. At roughly the 14 day mark, hit everything else that's green with another application.
  
• Optional but recommended: level out your soil and make sure it's flat, to help with a uniform look.
  
• Not recommended: tilling. It helps stir up weed seeds and encourages weed growth at the same time that you're trying to plant grass seed.
  
  Mid/late August:
  
  
• Seed with your given grass type. Do this at least 7 days after your last glyphosate application, 14 days afterwards is preferable. I suggest seed as opposed to sod because it's cheaper. Seeding is kinda its own post because you may need to cover with topsoil, flatten ground, irrigate, yadda yadda yadda. We can talk more about that when the time comes. ($10-$100)
  
• Add a starter fertilizer with your seed. Whichever fert you choose will be based off of the results of your soil test. ($10-$30)
  
  After a couple months, you should have a pretty healthy crop of baby grass, and then it will go dormant for the winter. Not a problem. Once spring hits, start following this lawn care schedule from the Lawn Care Nut. Most of that guy's videos are gold, and I strongly recommend that you watch them.
  
  It will take a little time and more than a fair amount of patience, but I'm pretty sure all of that will (at least for the first year) come in under budget, and it will end up with the results that you want. Especially in the long run.
  
  EDIT(s): Forgot to mention a couple things. I had a little more whiskey than I thought.
  
  Geographical zone will be in the sidebar.
  
  Also go with a pre-emergent in the spring if you aren't adding seed. The most popular 3 brand names are Barricade, Dimension, and Tenacity. Their generic names are prodiamine, dithiopyr, and...tenacity? Honestly I'm not sure if there's a generic for Tenacity cause it's not legally usable in my state. But seriously a pre-emergent will cut your weed problems down by SO MUCH.
  
  Estimated cost for the first year is $214 (minus water, topsoil/peat moss, and possibly tools such as a hand pump sprayer and a broadcast spreader) at the most, and $114 at the low end.

I just ordered this. Here in New Mexico I need something that can act as a post emergent for the warm fall season.
