When investors are looking for projects to invest their money in, one of the first things they look at is the projects website. They are immediately turned off and immediately quit research and deem the project "junk" when the see poor english grammar. English is a tricky language, you cannot simply use software to translate.
I can correct the broken english errors on your website and help provide a more professional look. DM me, thanks.
Before you correct the English of others, why don't you try to fix your own English first, it seems that you need it more than other people. If you really want to earn money from correcting English of others, make sure that you know it very well to be able to earn money from it.
