Here is some feedback concerning the layout:
You use three different types of summing up aspects (bullets, numerals and letters).
This makes the layout a bit chaotic. Think you can better stick to one type: bullets.
At some points in the text there are - - - - - lines.
They have no function at all for the readers (but maybe for you).
It doesn’t look professional. Better delete them.
The paragraph titles are rather long.
Short(er) titles give the text more power.
When will the platform start to work? >>> When do we start?
What happens after making a pledge? >>> Making a pledge
The Budget Overview paragraph is rather long. And technical.
Costs of the Marketplace of Online Go Lessons: Maybe interesting for webdevelopers, but hardly interesting for others.
Estimation of costs: A graphical representation (a pie chart) works better.
Why must niche platforms charge more than platforms used for any kind of business?: Why is this interesting for web visitors?
It feels as if you are apologising, which is unnecessary, and also provides readers with a reason not to participate in your project.
