Import XLS into SQL table, using .Net 4.0

Hello and thanks for viewing my project. This is the first time I have to post a project like this. I hired a worker to do this work for me. it was delivered working. Now it is not working and I have found errors after further testing. The challenge is, the worker is not interested in helping update their code. So now I post a new project to find someone else. VERY IMPORTANT It is your choice. You can choose to update the errors from the pervious developer OR you can fall back to previous code and start over. I have subversion. This functionality is part of an existing page. The rest of the page must be left at the most current version. I have written detailed requirements documents for you. One is for the full build and the other identified all changes that need to be made. IMPORTANT - the delivered code must meet all requirements of "Phase 14 v5 .docx" file that is attached. This is the full requirements document. Thank you for your time. ## Deliverables REQUIREMENTS FOR CODER The following is a detailed list of qualifications and requirements for a coder LANGUAGE - Must be proficient in Web Forms Asp.net v4.0, C# on the back end, - Must be versatile in client side JavaScript utilizing JQuery as needed - Must be able to implement Ajax server call backs using JQuery + web services - Must be proficient in subsonic 3.0 and/or Entity framework 4.1 for DAL code.
