Welcome to the HSBBW mmorgan. Sorry that you haven't received a reply to your post until now.
Your situation is difficult to comment on. It's not that often you find opportunities to move to the next level when your only current playing option is casual ball. Some here might say this is an impossible venture. I say give it your best shot. Who knows how it could turn out. Besides, there are lots of employment options in baseball. If you don't make it as a player, maybe something else good will come of it. If you're really serious about pro ball, then do as you've already mentioned and try everything to get noticed. Just make sure your game is at it's peak when you demo it. Good luck
