.net development

Hello, I have an old site http://bit.ly/lOkY6l that is written in .net many years ago. I need to move it (inc MS SQL DB), secure it & add the following functionality:
1. Use the data in the database for each application to build/populate a PDF final report. Once the report is created I need the status of the application to change to complete & update the user who can then download the document.
2. I need an email facility that sends reference requests to the applicant's employer. The employer must be able to complete the details online & then the application must update accordingly.
3. Add an existing payment processor to take payments for each application submitted
4. Change the current user type so that we have just 2. Prepaid & invoice

I can provide full requirements however at this stage please express compitence & interest in the job & we can move forward from there
