Are there good doctors in Dallas, TX?

I'm 30 and have been gradually losing hair since early 20s. I would say I'm not in a severe condition yet as shown in the picture, but I would certainly could use more density. So I decided to go with the transplant. I have recently consulted with a doctor name, Verret in Plano, TX (www.drverret.com), who said I only need 500 grafts, which seems too low for me and quoted $3750 for it.
All I want is a second opinion whether this guys is legit and the price is reasonable. I've also set up an appointment with Dr. Aroch who is a member of IAHRS, but want your expert opinion.

Thanks bunch.
