Unfortunately, the managers with the good connections wont act your manager before you've managed something to get you a rep..but there are a lot of peeps out there who are managers and willing to help you...just ask around...a lot of them just won't get you to where I'm guessing that you want to be.
Start of by pushing your beats to everybody, just throw white label cd's at everybody, just rememeber to keep it simple, don't forward too many beats, incl. your phone #, e-mails etc on everything (the jewel case, the cd etc) because I've heard stories of A&R people who actually liked what they heard, but when the material reached them, only the cd was left no phone # etc was listed.
Go to shows and give your beats away to the artists performing also.
