I need you to research on internet about the "E-commerce Platform Business" and prepare an investment proposal which I have to present to my investors for a new unique portal we are building. Here is the data that I want you to include
1) Total Ecommerce sales in last few years ( Along with the top 5 portals with max sales)
2) Expected sales in coming years
3) Commissions earned by E-commerce portals
4) E-commerce business as a whole
This will show our investors that this domain is profitable.
