Create new (client) folder using request form

When a sale has been confirmed, we want the salesperson to be able to submit a form to:

1. automatically create a new client folder (the folder name is specified in the form, and it's a subfolder of a parent folder named "Clients") and

2. duplicate an onboarding project from a blueprint, and

3. place the new project in the new client folder

4. with the client's name as the prefix to every task in the project

I have been able to work out every part of this form EXCEPT the first step - "create a new client folder ..."

is this possible?

Many thanks,

Gina
