ExtJS frontend development

Hi, I am looking for a programmer with extensive ExtJS knowledge to code up a UI building app. I have created a mock of the application with some functionality implemented in Sencha Architect and will provide you with this project. You can see the project by going to [login to view URL] The area that requires the most attention is the Views section which should allow users to drag components from a list of available components and drop them on to the view, either as a new row or column, or inserted between existing components. I am only looking for the front end functionality to be implemented, with consideration for adding new components, field types, actions etc. in the future. It is not necessary to perform any backend development or even provide mechanisms for connecting to a backend. I will add the functionality to push live data into the relevant stores and pull data from the stores myself. You are free to define the stores and models in any way you see fit and even make minor changes to the UI if you need to. The only requirement is that the view designer exposes the hierarchical structure used in the layout, so I can reproduce it exactly in the main app. It is also important that the system be developed as modularly as possible as features like the view designer will also be used in the form component designer for example. If you are interested in undertaking this project, please let me know how much you would want to do it and how long you will need. If you require any more information please let me know. This is an on-going project and there will be lots of development opportunities for creating new components, widgets and actions etc. as the project progresses. I am hoping to build a relationship with a developer and be able to provide lots of additional work in the future. Regards, Paul
