Sencha Architext - ExtJs Project

Require a web programmer / coder experienced using the ExtJs(sencha) framework, using Sencha Architect, to help accelerate our developpment of our Fleet Management System (Version 2). Developper must deliver Sencha Architect source that can work and opened by Sencha Architect Windows version. Essentially we want to create the following below : A main dashboard panel containing other connecting panels (Tab Pannels) / modules, Each element of tabpanel will contain Form panel to add/Edit data, and grids, to do CRUD (Create, Write, Update, Delete) and Grid to list of data. With interaction (sending data using Post, message box or popup telling that data has been saved...), All displaying and sending data in JSON. You do only Front end at this step, not need of php or java, Modules (in tabpanels) are : - Driver Management CRUD and list, photo, search... - User Management CRUD and list, photo, search... - Vehicles : Edit and list only, - Documents : Vehicle card, insurance, fuel consumption, Spare parts At this version, only desktop application. We need something that's professional looking yet cool at the same time. Chosen freelancer will have the chance for additional work in the near futures (Mobile version of our system, ...). We will prepare together an Excel document to define each task and his money ( Example : - panel update and list vehicles : 10 usd, - panel module XY : 18 usd, - panel module XYZ : 18 usd, ... ) There are a long list of Panels modules. Because only ExtJS Sencha Source (Front end only, not need php and java), I would like to have this project complete as soon as possible.
