Multi-Site Solution or Plugin for adding text to pre-written content pages?

Hi All!
I'm looking for a plugin or solution to add text into pre-written content on pages of a multi-site website. For example, I would like a multi-site customer to be able to fill out their Business info such as: Name, Company Name, Address, Phone Number, Email on a form. And then have this information populate onto pre-written content pages on a website template using shortcodes or a plugin....

Example:
[Name] Bob Smith
[Company Name] ABC Realty
[Address] 123 Main Street
[City] Anytown
[State] California
[Phone] 555-123-4567

Pre-written content:
Welcome to the [Company Name] website! My name is [Name] and I am the founder of [Company Name] located in [City], [State]. If you have any questions, please contact me directly at [Phone] or email me at [Email].

***Is there a Multi-Site solution (plugin) for this that you could help point me to?

Thanks in advance!
