I need a list of potential client leads for my business. It should consist of as many builders/contractors in the UK as you can find. I found on a couple local directories that there are well over 10,000 plus smaller operations. I would like a list of atleast 10,000. If possible more. Each listing must provide company name or individual name and an address. If possible an email address but not necessary. I leave the methods used to you. Also not required urgently can be done over a few weeks. Leads cannot be repeated.
