Honestly there is not enough information to provide you good advice.
There is no ONE approach to sell whatever website / company / solution. The strategy will depend on the nature of the assets you want to "sell" (your expertise, employees, code, customers, etc.), your potential customers (an entrepreneur, a medium company, a Fortune 500 company, ...), your balance sheet, etc.
So my advice would be to analyze your situation and try to identify someone who already sold his company with a similare situation and contact him. For sure (s)he will be happy to share his/her experience. Also, you could find some VC or investor and just invite him/her for a lunch and have a productive talk (it worked amazingly well for me).
