You are going to need Form builder, Universal email, and Digital File Pro.
Contact sales and get all or part of your previous perchase applied toward the extension library so that you will have all the tools you need.
You are going to want to apply the digital file pro server behavior for each of the specify file fields in the form. That will allow you to take the files from the form and place them in a directory of your choice.
Then apply the universal email server behavior on the page and you can build up the email including attaching the files you uploaded.
