I'm going to have to ask you to clarify your statement above...
I'll assume that you're SEARCHING for a Professional Dealer in the Leicester area... In which case, after you confirm this, I'm sure that one or more of our members may be able to help.
Because, well, basically, if you're a Professional dealer, looking to buy kit from our members based in the Leicester area, I'd have to say that you'd need to use the "contact us" link at the bottom of the page, and ask for our advertising rates... Of course, you'd probably be looked on more favourably in becoming an advertiser if you'd done that BEFORE posting on the general forum.
