I can develop web-crawlers that run on any website you specify, analize the html content, and collect the specified data you want. Content of almost any website can be analised with this techniqe, but before you pay the money, send me the website, and I'll do a free analisis how hard is the problem.
After I need some time to build and tests the bots, and when they are ready I'll let you know. Then depending on how many data you want I'll start to run these bots from a could and build a database. This can also take some time. When it's done, I'll send you the data in any format you want. Later this can be automated, or extened or etc..
This is a good techniqe to monitor other rival companies, monitor the market for a specific brand or item or anything, it's up on you. Data is the most valueable thing in our world, and I can offer it for a cheap price :)
