call rapid marine group. They do them!
They are a long way from Lakeville
The old R&R Marine in Shakopee is now part of Rapid, not close to Lakeville but not all that far.
I'd suggest the Faribault area, I don't know the lakes that well but I think there are some resorts and I know there's a baitshop or two, they would be good starting points. Good luck.
