105667 Requirement spec for a game

Functional requirements / use cases / wire frames for a ‘real life puzzle website’ I am creating a ‘real life game’: solving puzzles with the family in the countryside in the weekend for fun. All puzzles and actions will be directed from a website, all information about participants, their actions, status and financial information will be stored in an underlying information system. I am looking for a person or a company who can write the functional requirements. I ask him or her to produce the following deliverables: - a written down crystal-clear functional specification (in Word or compatible), - based on use cases, - including the 'wire frames': the structure (pages, fields) of the website without the design. These functional requirements are input for the website builder, upon which (s)he can build the technical specifications and build the website. The design, technical specification and building of the website are not part of this project. Quality is very important. Therefore I ask a , proven experience and traceable references in similar projects. If you can give me a draft for this, it would be easy to me for select you. Thanks!
