I spend many hundreds of pounds with Pro2col each year for commercial printing and am happy with their prints.
I will never ask them to scan a film again and will never, ever ask them to Photoshop a scan - ever.
But you take them as you find them.
They have an Imacon film scanner and I'm sure they will have a professional flatbed.
To be honest Leopold, a competant operator using a consumer flatbed scanner will achieve the quality needed for your purpose. Consumer units are by no means 'crappy'.
