Need help setting up my own craft business please!

Hello! I have been trying to set up my own art and craft business for over a year now, so far so good, but I need to expand and I have put in all the money I can afford. I'm looking to raise £500 so that I can purchase more stock and start to branch out with advertising (business cards,flyers,website) My goal is to be able to go full time in this business adventure, as currently I am having to juggle this arround a full time job. The more I can advertise and get out there (I will be able to start doing craft fairs) the better!
