make a living renting tubas

Tubas have never been so popular.  But the price of a quality tuba is out of the reach of the ordinary man.  Therein lies a business opportunity:  tuba rental.  With some seed money, you can aquire a set of tubas and get renting immediately.  Soon you will be living the good life as you collect the cash from your happy tuba-playing customers.
