If you know about fertility tests!

Am
If you have had to deal with fertility testing, please let me know how to go about it.
I know I can have children, but my husband has never been checked. We have been making phone calls like crazy, and everyone wants us to go to a family doctor, get a referal, go to another doctor, get their referal, and finally get his sperm tested. 
Why can't we just pay to have his sperm tested, without having to go through the other steps first? Do you know how?
 We need to know quickly, because I have a career opportunity coming up in two weeks, and my decision has a lot to do with whether or not we can have a child. I connot get pregnant for a long time if I take the job.
