Need a simple to use but robust CMS

I'm new to CMS and开发者_C百科 am fairly inexperienced with PHP and have no MySQL experience, but I need to find a CMS that I can have developers edit and change to what I need. There will be a lot of photos involved. These are the features that I need:

Administrator level to: add/edit contractor info., create work order for contractors, have work order emailed to contractors automatically, check contractors' answers to forms (refer to contractor section needs), send work order back to contractor if inadequate otherwise submit work order, work order information sent to websites for the company's that we receive the work orders from and fill in information and upload photos to the their sites correctly, and

Contractor level to: view list of work orders to complete, fill-in forms to answer questions about work order, upload photos of work being completed (the photos need to be archived and relabeled depending on whether the contractor uploads them as before, during and after work is completed, submit info to admin for review.

Quality Control level to: view all completed work orders, choose work order to perform QC for, fill-in form about work order, upload photos if work order was not found to be in good order, submit back to contractor and admin if deficiencies found otherwise submit congratulations letter to contractor and send update to Admin.

The photos of the work orders need to be over 640x480 and need to be tied to the work orders and not just go to a pool of photos. The work orders need to be searchable so that the Admin can find any work order completed ever. I'd also like to be able to upload previous work order information that has already been completed so that I can have all of the work order information in one central database.

All of this needs to be dynamic and protected from attacks and hackers. I've looked at Joomla and I'm overwhelmed by the learning curve there, but if that's the best option, then I'll start learning. I just wanted to get some ideas for stable, safe systems that can handle and help organize large amounts of data. Any help or advice would be appreciated. Thanks.

When you have so many particular requests and are not a programmer, chances are that you are better off choosing a paid solution. That is, hire people to do what you want for you. Open source CMSs are not always the better solution, even if they are free.
