Most commercial analytics publications will report on sampled data. I'd be cautious about potential biases. Instead, could you collect your own data for through Excel PowerQuery for analysis?
I agree with Yulia: unless you have strong reasons to prefer data from a company (for example, access to historical data), I would definitely build my own dataset. It is not extremely hard to do it, specially if you have some computational skills. But even if you don't, there are ways to circumvent it and get your data. Should you have more questions, I'll be happy to help.
