Researcher for technology project for elders

I am looking to invest in a company that plans to offer a solution to elderly people, to help them in the event of an emergency (i.e to get them help when they fall or have an accident when alone).

Before I consider this investment I need to understand more about the market, therefore I need a thorough researcher to do in-depth research and write a report on technology used currently. Typically there are smart watch type solutions and other room sensors and solutions available to puchase and on monthly subscription.

What I need:-
1. Report on all the existing solutions available around the world, some details about each, links to websites and the cost of each solution (up-front costs and recurring monthly costs)
2. Comparison between the solutions available, ideally on a single page spreadsheet
3. Details of any solution providers or crowdfunding/student projects that are doing some interesting things in this area and may be interesting to invest in

I have put a nominal price on this job however please reply with what you believe is required and any examples of previous tasks of this kind you may have done to give me confidence in how thorough and structured you are

Thanks!
