We are near Paris in France, and we work with 2 3D printer, Creatr dual and Creatr HS. Our printer have now more than 1 ant 2 years old !
We are looking for someone or a company to do the maintenance, this is impossible to find.
I'm pretty sure there is nothing you couldn't do by yourself.
Would be please to help you by phone if I'm able.

What sort of problems are you encountering with the printers?
Did you try contacting leapfrog support? As Dominique said it could be something you could do yourself.
