I'm putting together a model to determine the size of company I would like to purchase. I'm wondering if anyone has any experience on what return investors are looking for with ETA type investments. Is there a good range and minimum investment size investors are looking to make?

With the equity I can put down, I'm looking for a small investments of ~$50-150k from investors and trying to determine what's a reasonable assumption for how much equity they would want in a 650K SDE business.
