UI Design for List Manger

I'm looking to build a list manager that will ultimately have the ability to manipulate items within the list. I have a prototype but it needs much modification. It would be nice if the prototype was "functional" but probably not necessary as I'm sure it would involve more time and cost. For those who are interested I can send more details.

I'm fairly certain I have a very skilled developer for the project. I would like to create a UI to illustrate the required functionality. But should he be unable/unwilling to continue, it would be nice to have a developer here complete the project.

Functionality within the list is the most important aspect of this project. But there is much more design and functionality that will need to occur. I'm just starting with this very simple task to assess the interest/capability of developers who may be interested. I'm really looking for a long-term partner as this software will need continues modification/improvement over time

Thanks for your interest. I will provide further details by request.

I should add that I have the vast majority of the design completed. Now I'm looking for a developer who can make the UI come to live and get the software actually functional. It will be used to manage medical problems and perform CRM functions.
