My first start-up was a medical tourism company.

It's basically an affiliate business model: you get 5-10% of the cost from the doctor, hotel, and airline (depending on your negotiation skills). $500K revenue means $25-50K in true gross revenue for the company. Their net profit is $3-5K on that revenue, depending on how efficient they are.

I put my business on the back burner for 2 reasons:

1) 5-10% of the cost of the package is your true revenue before overheads, so the it's not very profitable once you consider your expenses. 2) It's a high touch customer service experience, so you can't scale it profitably (people will not buy an operation via e-commerce like they would an e-book: there's a lot of personalized contact and questions, examination of records, etc.).
