Custom Database Development

We would like to create an online job application (that has five parts to it) for applicants to be able to submit to us. Basically, we want the first step for them to create a username and password with us, then begin the application with a save at the end of each page. It could take some time for an applicant to fill out the entire thing, so we want them to be able to close and return at a later time. We also want to be able to receive email notice of a new registered applicant, and have a back-end where we can access (view/print) a copy of the application in some sort of easy-to-read format. We are a web development company, but this project has grown outside our in-house programmers' expertise. I do not really care much about the language/database used, but we want it to be easy to install (and integrate into the web design). We need this completed ASAP. Thank you, and we hope to find someone to help us out!!!
