User Management System

Hi, I'm desperately looking for something I need for my startup. I have a payroll business and am wanting to expand to include online payroll features for my website. I use WYSIWYG Web Builder to create and edit my website. I have no coding experience so I need either a 3rd party software or website to help me out, or someone I can pay a fee to complete this for me.

1. I want them to be able to create an account on the website. Then they can see their personal profile page.
2. I don't need them to add all of their information to create the website, but after the account is created, I need them to fill out the rest of their information.
3. Then I need them a page to add, edit, delete and view all of their employees. And maybe a table or something for the user to enter the hours for each employee and then can hit a submit button. The data can just be sent to me via e-mail or by being connected to an excel spreadsheet that is updated when they submit their data.

That's all I pretty much need. I know it's going to require a database for that information to be stored and retrieved. I know that the pages will have to have a good amount of security and protection as it will have private data stored on these pages and in these databases.

I know WYSIWYG has a user login system but it's rather simple for what I need. Is there someone rather cheap that can work with me on building this or is there an open source software or something similar that I can use to help build this. Remember, I have no coding experience of my own. I'm tech savvy, just not in that aspect whatsoever. I did see something regarding something called "CRUD". Not sure if that can help point me in the right direction. If anything, is there a web builder that does do this I can switch to?

I see user login systems on just about any website where these functions seem to be available and easily implemented. Even on this site. This seems to be a common feature available everywhere and on almost any website but I literally cannot find a full length tutorial or 3rd party to help me out and I've been looking for weeks.
