How to sell app company

I have an app company, consistently grossing $50k+/mo. I'm looking to diversify my exposures and move on to another project. So, I'm hoping to learn from you about the possibility of selling the company.

1) Who is the likely acquirer? The company has a portfolio of apps spanning many different categories. I'm not certain any one of them would be valuable enough to a strategic acquirer, and yet the portfolio might not make sense to any one acquirer either.

It could make a lot of sense for an individual or app company that knows the business well, but do such parties have large amounts of cash sitting around?

2) Where/how do I find such interested parties?

3) What are typical valuations/terms?

TIA
