| The non-regional things I rely on are
1. references by customers of the "project manager" (called a "contractor" here in the US), and
2. input from people I know who have had similar work done by a contractor.
If I am not happy with #1 and cannot get #2 I rely on local sources that will no doubt be much different in the UK.
I don't know what they call these groups in your area, but around here a good source to start with is the local Chamber of Commerce, a group that maintains a database of local companies and their reputation.
Can someone from the UK help Mongoose with the right group that would help her pick a good contractor? |
