Is this an option?

I own a Real Estate company. I need a form that my agents can upload they contracts into where they can then be stored on uploadcarw.com. Can this be accomplished?

Yes, that's possible with Jotform.

You can create a form with Upload care if you want, here's the guide: https://www.jotform.com/blog/uploadcare-widget/
