You need to create your own marketing ploy of some kind. But if you start small and let the business grow as a glorified hobby, it might turn into something more. Depends on the size of your town and how many people you can talk into vintage vacs.....you should also fix the plastics fantastic whether you want to or not....just for the income and reputation potential. You've got 'kid factor' going for you....lots of people will be more patient with you than they would with adults.
