I recommend you take a wander thru a light industrial area on a Friday afternoon and hunt for a small jobbing engineering firm, they could do that for you in about 5 mins, probably cost you a carton.
Or, do a search for any local Model Engineering clubs, the kind of clubs with small steam trains that take kids for a ride, they have their own workshops and/or have members with workshops and will also only take a few mins to do that.
