2 players looking for a Dynasty Start-Up League - Little to No Buy-In

My friend and I are serious fantasy football players and are looking to join our first Dynasty League. I work with the NFL and unfortunately I cannot play in a league with a buy-in where the prize can be over $250, so we are looking for a league with a prize less than that or no buy-in at all. Let me know if you have 2 open spots, thanks Footclan!!
