Functional Specification Required

I need someone to help create a functional software specification. The software is a web-based line-of-business application. The screens in the application will perform simple CRUD operations on a database. There will be able 10 screens. I will provide: - details on the fields required for each screen. - prompt payment for completed tasks You will provide: - an estimate on how long you expect to take on each task. - a word document which details the application, with change tracking. - various Axure v7 prototypes that show the screens and various use-cases and states. - work tasks will be tracked in an instance of JIRA, which will be used to measure estimates and also time spent. The successful freelance must be able to provide evidence of: - EXCELLENT written English. - Current working experience of Axure v7 - Current working experience of MS Word - Current working experience of Jira v5 - Experience of writing technical specifications I will provide loose requirements for what is required, and I would expect that the specification will go through several iterations before it is complete. I will provide a milestone payment when each iteration is completed. On each iteration I will provide more information and details of any changes that are required. The duration of the task is open ended so I need to engage someone on an hourly basis.
