I Am 30 Years Old. I Appear To Be Very

I am 30 years old. I appear to be very healthy. I recently discovered a small moving mass on one of my testicles.
I do not have health insurance. Where would you suggest I go to have an affordable ultrasound completed?
Also, how do I find a urologist or can you recommend someone that I can pay out-of-pocket for office visit?
I live in the Holiday Florida area, zip code 34691. Thank you.
