meh, its really not that difficult. If you make beats and you want to be the production company, its really just a matter of making it legal, for taxing purposes. First step is to register the business, likely as an LLC, and get you 401k and all those tax things filled out. If you have a lawyer, they will usully do it for you for a few hundred dollars.
After that, you will probably want to register with ASCAP or BMI or something in order to reserve your company name with them. Actually, this could be the first step just so you know what your company name will be before you actually register the business. Honestly, until you're dealing with major labels and selling beats on the regular, this isn't a huge deal. Until you're making too mcuh money to hide it from the government, you don't need to register the business...
