I would like someone to perform online market research analysis for me on the online tutoring market. I would like to know how big the market is currently, who it caters for, which subjects are the most tutored and which ones are the least. What are the names of the companies and websites doing online tutoring, can they be visited only with a subscription, how many members do they have, how profitable are these websites roughly? What are the iPhone and Android apps that cater to this market? What are the main problems or complaints people have with each of these tools? Identify all online tutoring businesses for sale, their sale prices, the websites involved and relevant links. Lastly, identify programmers or websites that are good at creating relevant websites. Thanks! Anyone who can provide an example of similar high-quality work they have done for someone else will get priority.
