Start selling on the streets of your home city. whenever you go to a show (which you should be doing on the REG), make sure you hit the DJ, radio reps, etc. try to get in good with the owners of the spot.
Make sure that you are on your grind and think business every time you step out of the house. Although I do make money from selling beats, I have yet to dive into the leasing process of beats. I just sell them straight up or print copies of contracts, that insures people get me my back end money. Those are really the only two things I do.
Hit up smaller publishing companies and read what they do for artists. ascap will only deal with huge numbers if you are really out there, not to say that they won't deal with you.
make sure your copyright info is up to date and make sure that you are in a place to maintain constant contact with the people you are selling to.
They may want to come to you again or get you gigs in the future, if that's what you are looking for.
Selling beats is hard and it sucks really, really bad though in the end, because there is not a lot of money in doing it and there are rarely people are that are making a living just and only selling beats.
You have to be able to properly and thoroughly mix and produce songs and be on your stuff about studio jargon, from crescendos to whole and half rests.
Producers make the real money. the ones who's hands are the last to touch the final product before it's shipped, shopped around to a&r's or sold. I mean, getting in the streets yourself and just selling, selling, selling.
The industry is WAY different from just a few years ago. we are back to the Wu-Tang standard now. every man for himself. out the trunk, backpack, hitting shows, throwing parties, etc.
Get your grind on.
