The thing is, a couple of hundred is going to cost not much less than a few thousand so it's worth spending the extra few quid and getting a boatload of them. You don't have to shove them all into houses and businesses straight away. Other giveaways are going to cost more money, as things grow for me I'm going to get keyrings done, I can get them for £1.50 a pop for 300, I'm also looking at mugs (no one ever has enough) give them to commercial customers.
There's loads of marketing stuff you can do that won't cost you massive amounts of cash mate, get your thinking head on, it will pay off. Like you, a few months back I was ready to throw in the towel, this month I'm looking at a turnover of 3.5k
I'm not prepared to put my profit on open forum but trust me, it's worth getting out of bed for
