Serious Drupal Team/Company Needed for Long Term

Hi, I am looking for a serious team who can handle multiple drupal projects in time and also very good at communication. I have lots of drupal projects and for those I will need quote from the selected provider time to time. So I will expect those replies very fast. Also this is very important that someone responsible from the selected team must be online on his time zone through any IM to answer any queries. Currently I have 2 drupal projects to start at a time. Also 2 half done druapl projects from previous provider on whom I can not reply any more. So I will need the selected provider to take over those projects and complete asap. Please bid with your portfolio and on bid amount please specify your price for a PSD to drupal theme conversion rate. Serious Bids only with drupal portfolio. And I dont want any individual to bid who can not handle multiple projects.
