LIVE Broadcasting to Satellite Company in L.A. ????

Hi, we are planning to Broadcast (live) from Los Angeles to Mexico and we are looking for a COMPANY in L.A. that offers transmission to SATELLITE link communic. services (in order to broadcast alive), and because we need to be interacting in realtime we mostly need a company who can offer uplinks to satelite, not only streaming video
it's been so difficult to find qualified companies

Does anybody knows any company that can do this LIVE BROADCASTING LINKS ??? we have the video-audio equipment, but we need the transmission link
