How to build a catalog of companies

Hello!

The website I’m currently working on must have a catalog of companies, so that each company will have its own page. Upon registering company should fill in a form with some information about itself (like company name, location, address, logo, etc.) and this information must be published as a page on a website (all company pages will have same field set). And there also should be a voting system. Upon registration, each company can vote for up to 10 other companies. Votes sums up at company profiles (pages) and this builds an overall company rating. A summary page should display a table of all companies with each company information and their ratings (I plan to use some JavaScript libraries to make it sortable).

I hope somebody already had similar task done and there are some plug-ins out there that can help to get the job done, to avoid very heavy PHP programming. Can anybody help with an advice, please?

Where is it better to keep company information:
On WordPress pages and then access all company pages and pull company information to build a summary table?
In additional metadata fields in user profile and then build a company page that pulls this data from there?
Directly in database table and then access it from a company page?
Performance-wise, total number of companies is expected to be up to one thousand.

Please help with your advice, honestly, I don’t know where to start.

Best regards and many thanks to everyone responded!
