Custom Design Data Entry User Form for Entering Customer Information

I've been searching for something specific that I was hoping that someone has already made, but I'm not finding what I need so I'm hoping that someone here will be able to help point me in the right direction.

I'm creating a make-shift CRM for my team that'll allow us to save all of our client information that we individually collect into a central database/excel wb. I have a macro that was created by someone on this forum (thanks arlu!) that will be pulling the data from multiple work sheets (1 per user on my team) into a centralized database.

What I'm looking for is a way to create a custom user form that'll allow me to enter in information designated to a specific cell. Right now, I have 28 columns that'll need to be tied into a text box on the user form. Only 3 boxes need to have data entered into them in order for the user form to accept their information and place it onto a work sheet. I'll also need a way access this data entry form from a work sheet relatively easily.

Thanks!

Also, I've come across these solutions but they're not quite exactly what I need, but I will point out what about them I like.

I liked that it has the ability to post the date of when the button was pressed
Easy customization

Anybody? Maybe point me towards a thread that's already covered this and I can start building my own?

bump.

Starter code? Help! please!
