Planned Parenthood does a standard STD test for gonnerhea and claymadia for about $40, they do an HIV test for free.
If you want tested for something else like genital warts or trich or whatever, you have to let them know what you want to be tested for that isn't included in their standard test and they will give you the additional fee if there is one.
Nice thing about planned parenthood - if you can't pay the entire bill, they will let you make payments on the balance due.
Anyway give your local Planned Parenthood a call and they will tell you exactly what they test for and how long it takes to get results etc.
Also some PP locations have the female condom available, you can ask if they have any they can send you home with as well.
