BGP Peering Info

I am trying to find out if any upstream providers that offer BGP to downstream providers, use any type of "form" ? I am curious as to what type of questions are asked. For example; full route or partial route (if partial, how many), do they offer route reflectors, confederations, multi-homing, or route filters?? If anyone knows of an upstream provider that offers BGP peering and has a form that I could look over, I would greatly appreciate that. Thanx
