Seeking Freelancer with Experience in Doing Patent Searches

I'm seeking someone to help me about 5 hours a week (20 hours a month) to conduct patent searches.

An example project:
I"ll say I'm interested in making a similar product to the below, please give me a summary of what specifically is patented and protected and then provide consultative suggestions on possible changes I'd need to make to not invade any existing patents.
