Hello ,
We read your requirement document attached with bid & understood that you need online student-tutor portal where both can interact with each other through website using web cam or video sessions. It would be nice if you do reply to following queries.
1. Who will be target audience for website in terms of marketing?
2. Which payment API you will prefer for website?
3. Will user able to rate tutor after session is over?
4. Do you need to run membership on website?
We will suggest you PHP as development platform for this website. Also we will provide you flexibility in payment terms where we will divide it in two installments one you need to pay after completion of design phase of website. & remaining you need to pay after completion of development part of website.
Consider this as ball park estimation we will provide you fix time & cost estimation once we fix the requirement in deep manner.
Cheers,
