I want to buy a business and incorporate Bitcoin into it. Here are some requirements:

1. It has to be profitable. That is cash-flow positive.

2. It has to be relatively simple. No crazy specialized knowledge required.

3. It has to have been running for a long time.

4. It has to be something that's reasonable for me to buy near Austin, TX.

The goal would be to see if I can incorporate Bitcoin into it and see how well I can run the business.

Any suggestions?
