I need an extended sales database!

Hi everyone, first ad so I will try and get all details in. I am looking to have a database of around 1200 companies trading in the Construction & Recycling industries, all based in the South West of England - Gloucestershire, Avon, Somerset and Exeter. These can be any size; startup/sole traders through to well established partnerships. The essentials are that it is clearly organised and sorted geographically in order for me to see who is nearby when I visit various places on the road. I would need to have the company name, post code and contact number included, with the paid option of company directors as well. I already have a database of around 700 but need to cover as much ground as I can and I know there is plenty more out there. I look forward to hearing from you, thanks very much.
