Poorly done patent research on utility paten already there leaves me in poor house

Advent did a research on an invention that I had to see if there was another patent or idea similiar to mine. They did a very poor search leading me to beleive I had a good invention.

So many thousands of dollars later I still had to go to a patent lawyer to finalize what I thought was my idea. To my suprise there is already a utility patent on my (or what I thought was my idea.)

I have spent alot of money on this and now cannot do anything with this because someone else already has this utility patent.
