Kitchen worktop fitter

I am looking for a suitably qualified or experienced fitter for my new solid walnut worktops. There is a 90 degree corner joint that i would like the properly constructed and cut outs required for a sink and hob. Length of the worktops is 3m on one side and 2m on the other with a return of timber to act as a side panel.

Ideally someone local to me in Tewkesbury and available in the next couple of weeks.

many thanks
