I own a SaaS business with a family member, which has become a nice lifestyle business, but my business partner is ready to retire and I've become involved in a YC company which is growing like crazy.

There would be nobody staying with this company except perhaps one technician and a contract programmer, but the code is clean and the revenue is reliable. Hard expenses are trivial and there is good potential for growth. One good developer interested in business could run the whole thing.

Is there a good place to put a business like this up "for sale"?
