Bug fixes/updates to custom ASP.NET MVC SaaS/CRM system

We have a SaaS/CRM site that allows users to view there total monthly/yearly sales they have generated from the software service they are selling. The SaaS site uses an API for a recurring credit card subscription system that is called (CheddarGettar). This API allows our SaaS site to branch off to this hosted CheddarGettar Payments Page and capture credit card info or allow the user to adjust there subscription plan. -Need to have all of the reports/customer checkout process reviewed/modified to make sure everything is calculating and running correctly. -Need to make the reports have a CSV export option. -Various CSS / UI edits need to be made to make sure that when you press for example a Save button it will actually indicate that the settings have been saved. -There are some bugs that need to be fixed. When you delete something from the database it needs to actually delete the entry. Sometimes it will duplicate it. -In addition we need to have the ability to add some additional rows of data to the database and then have the option to link them to the. For example; You can setup "Account Managers" and then link them to "Resellers" via a dropdown box.
