I am surprised with your focus on bidding amount.
Are you interested in learning or want to pass your time?
If your first focus is on money, then plz ignore my bid.
The amount in the bid is only to grab your attention on my message.
If you are really interested, then i can help you even without money.
I prefer you to pay about 1000 units( of your native currency, i mean, if you are from rich country then more money so that the burden on you is less).
Try to learn how to respect a would be teacher.
