Thanks for your entire input guy's, it really is appreciated.
I think for this idea to get off the ground, I will be the one doing all the work and as quite rightly said, too many chief's!!!!
At the moment, I have way too much on to devote the time required. If I / we do go ahead with the project, it will have to be at a time where I can spend time working at it. I also think the best way would be for me to front the project.
The shop we we're looking at is ideally situated; however if in the meantime it gets rented to someone else then so be it.
Again thanks for all the advice; it's good to get independent input from people, especially from professionals in the trade.
Cheers
Ponty
