Buy tools. You can’t offer a service you ain’t is. 
Tools are money makers. Walk it out in the beginning. I had tools. Would walk out to biz with dirty windows. 3 hours later, $120, 20 and 30 bucks at a time. 500 biz cards are 20 to 65 bucks. I think flyers would be the better spend. Walk, flyer, work, repeat. Good food for thought. I have a gob of tools, and a gob of biz cards. They collect dust. I make money with tools.
