Asking for Advice about my next product Idea...

I have the craze idea to develop an SDR-Agent that will:

1. discover new opportunities on LinkedIn and Facebook,
2. contact leads and manage conversations on LinkedIn, Facebook, Email and Whatsapp;

3. provide a complete DFY solution, providing social accounts and email inboxes (so the users don't need to risk their own profiles).

Finally, I am planning to offer a 7-day trial for $1.

I have some concerns:

1. is there any room for a product like this in the market actually?
2. what may be the rate of users that will pay for the trial and will never use the tool?

3. can I bootstrap a project like this and run it alone (I have no partners)?
