Generate list of suppliers in UK counties

Hello, for this job, I'd like to generate a list of:

Shed Manufacturers
Shed Retailers
Shed Installers

In each county across the UK.

The data I'd like is:

Company name
Website URL
Contact email (or contact page)
Contact telephone

I'd like you to price this job for just one county, Bedfordshire, so we can take a look at the results and fine tune.

I estimate there will be around 20-30 results per county.

If we can crack this, then there are lots of other datasets I'd like you to work on.

Thanks.
