The ball is in their court now. I filed two pieces of essential paperwork a while ago, one to register my trade name ($25), and one for a tax identification number. I can't really move forward without those two clearing first. They haven't cashed my check yet, so apparently it's sitting in someone's inbox in Baltimore. Maybe someday they'll find it.
In the meantime, I'm ready and waiting to apply for my trader's license and my sales and use tax license. I'll also be needing a letter from the landlord stating that I'm not violating my lease or any zoning codes.
My Etsy store is all set up, but I can't list anything without that pesky sales and use tax license. *Sigh*
