I wish I knew how to make a company like this work, because I would like to do it.
Inexpensive raw materials
Inexpensive and experienced labor
kick-a$$ marketing
low logistics (delivery of materials & finished product) cost
a rabid, devoted, and affluent demographic
It would be a labor of love for you the business owner, as I understand the margins on beachcats and parts is almost non-existent.
