Interesting. First step is to validate your idea with the market: Set a minimum success criteria for how many customers you want to have on Day 1 to prove that the business is validated with the market. For example, set a goal to get 5 people to pre-pay for jet ski rentals and go to talk to people and get the sales. Set them in the schedule for Wednesday. Then make sure you have the paperwork and jet ski by then. Business validated. Go get more customers. Running it remotely within in a week... I'd have to think on that one a bit more.
