So, as your defacto brand manager let me help get you off the floor.
PURCHASE AND own your domain name visit godaddy.com (sometimes low as 99cents)
Purchase email package with your domain name so now you have (email@example.com or something like that). This helps you get away from the yahoo's, gmails and other web based emails.
BUILD an online store: visit sites like wix.com or freewebstore.com they offer templates and either free of discounted e-commerce sites (about $5 per month)
AFTER, and I MEAN, after you've completed all these steps above, purchase business cards at vistaprint.com (about $10) with all the proper information.
Now, not only is your business online, you look like you've spent time with a marketing guy helping you put things in order (which you have).
This is absolutely no guarantee you will sell anything but give you a more professional look and remember people do business with others they know and like. Who doesn't like a person with a professional business card and some sense about what they are trying to sell.
I recently seen the 1st show ever of late night with Jimmy Fallon. His guest was Will Smith during the dialogue he said "The goal of a person is to share their gift & make people's life easier". Wow, how easy to say and do. That's not saying work for free but each of us has a God given gift that others come to us for. If you think deep you can pinpoint it.
Use that gift of yours, help make the world easy for someone, give them a smile, word of encouragement, offer assistance growing their brand.
Just once correct the universe.
