Great, good luck with the tech, I would say you might not need his services (by now) because with your current setup you will get locals of New York, NY in SD from 119°W @ Transponder 20; Transponder 20 is a CONUS Beam not Spot Beam.
The company in Miami (Kiwisat) has a very strong footprint in Mexico, central America etc (Miami Locals in HD)......the 1.8 m will be almost weather proof for that SES10....(lol)
Unless you have a very good ISP the satellite could be a better option, you need at least 4 Mbps for a decent streaming; most likely very soon your area thru Elon Musk's Starlink will provide you a 90 Mbps + for $99 a month I don't know when you will have it available in Mexico.....
