Americans only - Need you to google search for me before building ( Read Info )

Here's the thing: I have a couple of website ideas that I would like to build for USA but I live in the UK and I don't know whether they already exist or not. That is why I need a freelancer from america to search google for me and tell me what they found - does it exist or not,or if there is anything similar. Then I might want to build it . Thank you!
