Hi,
I have a Terapeak account and use it to do some basic market research, though I do not own my own ebay & amazon stroe...
Your task interested me as I want to know more about the market and you have the actual biz needs.
I am in China, with a full time job for data analyst, and can work to do market research at weekday's night (avaliable London time: 13:00-16:00, ) or weekends.
I am good at Excel, R programming and data analyst, thus I am sentive to the data and identify the trend of the hotsales.
If you need, we can start with a small project, then to larger.
Small piece of milestone set.
Regards,
Airen
