Hi Sammykins, and welcome to Platinax.
First of all, best of luck with the new business - secondly, something you may find more helpful is distributing leaflets door to door for your services.
The printing business can be pretty competitive, and I'd expect you should be able to get 1,000 leaflets for under £50 (shop around and see what happens...).
Then if you locate a relatively affluent neighbourhood, drop the leaflets through the door personally.
I suspect that a basic investment of time and money in that way could yield some important leads.
Hope that helps.
