Usability testing and feedback

I am looking for someone to help me review the 'ease of use' of my new web application and where possible provide feedback and recommendations to make this application even more easy to use.

I am looking for a ranking score 1-5 ( 5 being highest) of every page, process function within the portal. Plus any additional comments on how the process, form, screen could be improved.

Successful bidders will be asked to create a trial account in my application, familiarise themselves with the application and its functions. The application is a secure collaboration portal, so it's functions are similar to those of a business user content management system.

The bid is open to anyone who wants to respond, but those that can show they have a flair for defining easy to use systems, who can demonstrate a proven track record, will catch my attention.

Bids under £100 only please.
