At the consultancy company i worked for in the past they would rent out dev teams in sprints time periods xD. As a way to get a foothold at a new client. First design do orientating talks about the full product. Start shaving away features for the MVP and sell the MVP as the first shot.

I found it quiet genius move from their sales teams. Because usually customer went well actually i could also use feature x, y and z that didn't made the MVP product.
