Mechanic Job in Saint Cloud, Minnesota

We just bought a 1976 GMC Vandura Midas Mini motorhome. Drove it about an hour and a half, stopped for a break, and now it will not turn on. Currently its sitting in a grocery store parking lot. We've replaced the battery and were suggested that it is probably the starter. Tried some tricks we read online and still couldn't get it started. Key turns in the ignition and clicks, dash lights and head lights are working. We're trying to at least get it back to St Paul, so even if we can only trick it in to starting to make the drive back, thats a-okay!
