I would put the £500 towards having a good website built, Nathanael Jones did mine three years ago, i tried local radio
advertising for three weeks, i didn't get one call, i tried local different city paper advertising for months here and there,
with a very low return, I absolutely swear by the website, i get all my work from it plus referrals from current customers,
its the best investment for my business i ever made.
