Andy remember that you'll not only need capital to buy equipment but to kick-start your marketing too. Many cleaners choose leaflets first of all, as they can be relatively low cost, but there are plenty of ways to start business rolling in.
A small, simple ad in Y/P (monochrome reverse copy) will undoubtedly pay for itself within a few months, forget Thomsons to begin with, maybe later.
Ignore the chumps that ringg YOU up proposing marketing and advertising ideas - they're only out to rob you of your cash to pay for their printing or some other cost that they need advertising to pay for.
Yell.com is worth doing. In my experience nowhere near as effective as the book but still returned me 500% of what I invested in it last year.
Forget the tinpot online directories, most of them only collect and sell on your contact details to cold callers. Read the T's & C's.
Remember that the most expensive marketing is not always going to be the most effective
