Sample Excel addin(repost)

Greetings, I'm looking for a developer experienced in writing addins for Microsoft Excel. This project is for a sample addin that will extend the Excel UI and integrate with different features of Excel. All the integration points are listed in the attached document. The project does NOT include any logic development just Excel integration. You can ask general questions prior to bid acceptance if necessary. I have a skeleton of a COM addin that you can use as a basis for your work on this project. there is no need to develop an installer . Thanks,
