Keep track of the scope editors?

Hello,

I wonder if any of you could recommend me a proven tool (something like a CRM) to track the scope editors.

At the moment, I use a very rudimentary CRM that I did in MySQL and PHP and run XAMPP locally, plus a lot of large spreadsheets in Google Docs, but it's not the perfect solution.

I need something where I can track the emails I send to webmasters, their responses, the prices they ask to publish a sponsored publication (+ currency), their special requests, the other websites in their portfolios, their websites . Language, target country and a lot of other details. It is also a fairly long list of contacts, with thousands of potential partners and tens of thousands of URLs.

Any help will be greatly appreciated. Thanks in advance.
