That's awesome! I started back in 2011 and still actively involved (just not blogging) but its still very lucrative.
My other suggestion would be to apply for an Amex card which will
generally give you an instant card number if you are approved online when you apply. I just did this as I had to leave a $7.5k deposit with Mason title for my Poly resale contract and chose the Amex Business Gold which has a 95,000 point offer for spending $10k in 3 months. I only have $2.5k left to spend and I don't even have the card in hand yet
