How/where could I find what large companies are currently buying?

Hi, I would like to source a cheap ultra high quality products, to be verified in advance by independent verification agent who does sourcing inspection related to quality and accuracy, and ship them for higher price to the companies needing those products to solve whatever problem they have (e.g. required material to produce the final product). I plan to hire consultants here who would explain me step by step how to build the trust and reliability to get the deal approved with those companies even as individual stranger (suggestion by far beyond sending them a sample in advance). However, I am at the stage of one step before that. In fact, multiple steps before. How and where do I find out what large companies are currently buying, e.g. in smaller quantity? I said smaller because my budget what to buy from Alibaba to have this shipped to the company (and obviously change the label so it's not seen that is is coming from China) is very limited and I only want top quality products to be delivered so companies (my prospective clients) could really benefit from my help. But how do I research on what those companies are currently buying?
