Maintenance for 120 WP sites (ongoing contract)

Hello, IMPORTANT 1: we are looking for a COMPANY, not for an individual freelance. IMPORTANT 2: if you have not passed Freelancer's WP test, you'll be asked to do it, we won't recruit you if you have not passed this test and if you're not in the 5% best results. We have around 120 WP sites to maintain. We're looking for a company with several developers who would fix the issues we're having after some themes or plugins updates. This is an ongoing project. We're looking for a SERIOUS company, people who work, then test their work and report. People who take the initiative of contacting plugins developers to get answers to their questions if necessary. We want involved people in our team. Our work schedules: 09:00am to 08:00pm GMT+2 (France - Europe). A developer from your company must be available to talk with us during these hours. It doesn't mean you'll have to work immediately on the tasks we'll submit but at least, someone must reply in less than 30 minutes and the work must start in maximum 1 hour after we submitted an issue. Communication: through Skype, with developers in direct (no middlemen). If you have no history on Freelancer but on other platforms, let us know. If you have no history nor on Freelancer nor on any other platform, don't waste your time. We won't recruit a company having less than 4.9 and 100 reviews. As we won't recruit a company which has not passed Freelancer's WP test. Best regards, Florence.
