0. I was thinking to do very detailed specifications and have trial for a week. I believe there is no other way. Also during this week I could see how the base tasks will be performed and if it fails could cancel the relationship.

2. That is indeed very useful advice, if I could get referral. Unfortunately I could get those from the websites I could find the agencies or people. Do you think I could rely on these?

3. Useful advice, but what other places you would suggest. Here is good resource I found but any of these look main stream: https://www.forbes.com/sites/abdullahimuhammed/2017/06/16/79...

4. Ideally I am looking for 2-4 people for 2-4 months. Then it makes perfect sense for someone on the team to be used for the communication.

I would definitely check with you once I prepare the specifications (in next month or so).

Thank you very much for the input!
