I was hoping someone else would come along and give you the bad news.... ah, well. Here's the deal - there are no recording engineer jobs. Studios are closing left and right, and even engineers with 25 years experience can't find a job - and if they do, it's for shit pay. Everybody wants to do it themselves now (just like you), and coupled with the fact that artists can no longer generate any meaningful revenue, this is not a good time to get into the music business. On the other hand...
Obviously, some people are making a living at this. If you feel that this is what you must do with your life, give it a go (and I'll pretend it might work). From your post, will assume Vegas as a hypothetical base. Three primary areas to start with:
Business plan - Again, just assumptions from your post. What you want to do sounds like music production, possibly with engineering services (or perhaps a label). You need to determine the cost of startup, what you are charging, what services you are offering, marketing plan, profit margins, etc (even if only for your own use). Here's an
example.
Networking - get out there. Assuming Vegas, there are many small clubs and shows, with things going on every night. Go watch, introduce yourself to the performers and promoters, try to figure out how what you can offer will benefit their careers - and let them know you care.
Branding - determine a catchy name that is not in use (by a company or web domain), register the domain and create Facebook, twitter, etc accounts. Don't worry about content yet, you just want to make sure you're set up for social media marketing.
The way I see it, your best bet is to present yourself as a producer - assist with composition and recording services, marketing, and distribution. Since all artists are by definition starving, though, be realistic in your revenue projections. Here's an example, using Vegas again.
Digital Insight Recording is a pro studio, with hundreds of thousands of gear and properly treated recording space. And yet, you can rent studio space for $50/hour, engineer included. Pretty hard to compete when all you have is your home studio (and let's be real - certainly can't track multiple live musicians at home).
So, just throwing stuff at the wall - check out the scene for what you can add, do the business plan, figure out your business name and do the preliminary social media setup. Using Vegas as an example - you can set up an LLC online, only costs $75 bucks ($500 here in MA), and with the resulting docs you can set up a business account at any bank (deposit a few hundred bucks, call it a loan to the company, and immediately start writing off anything that could be an expense). Don't worry about credit yet - you can always quickly set up with paypal, but there are less expensive options. And maybe partner with Digital Insight - see if they'll give you a discount for bringing in artists.
Full disclosure - I've started a couple of (successful) businesses, but not in music. Wish you best of luck, and will help if I can.
