Fill doctor near Las Vegas for patient banded in Mexico?

Hi there. My mother-in-law and I were both banded by Dr. Lopez in Tijuana. She is ready for her first fill but doesn't want to go back to Mexico. She lives right outside of Las Vegas, NV. Does anyone know of a good, reasonably priced fill doctor near her. So far I have only found a good doc in Orem, UT and one in Ventura, CA for her. Thanks.
