one more coat of color won't do a ton of good to be honest. You'll need probably at least 2... otherwise there will be some streak marks. Trust me. I just got my car done, and I saw what it looked like with one coat. So, you're looking at 2 coats and 2 coats of clear. Price shop. Make sure it's good paint. Avoid Maaco, Earl Scheib etc. They're sh!t paint and it flakes. Look for shops that spray using Dupont or something like that. It's a good paint for a good price. Should be around 2,000. I'd say.... buy a really good wax... like a 3M or Mothers and go to town with a few coats. Or, spend 100.00 on a buffer and creme and buff out your current clearcoat. You'd be amazed at what just that can do. Hope I was of some help.
