How do i get a semi-pro football try out? or evaluation???

I have only played jv football, because i dropped out of school, but i stayed in shape, staying playing good athletes on the pickup bball court, (lived next to a division II school) ran the court with all state all conference players.....and didn't start training untill after HS, can't see myself going to college, even though i took some college talent to school...the GRADES you know....... im 5'10" 180......... with quickness and speed, and good PG hands that can be utilized in football, believe my body and athletisism is more built for football. SO how do i get evaluated or get a try out with little on field experience? Pretty much have to know somebody? I been trained by a top 5 pro welterweight boxer, who does have some connections in athletics, should i give him a call? any suggestions? im 25 by the way, was a track back up in HS, 100 200 meters....but have greatly increased my speed, any suggestions?
