Create sites automatically using existing site template and two external varibles

Hi everyone.   I would like to know if its possible to automatically create a site in an existing site collection based on an existing site template and pass two external variables.  The two variables are a projectName and a projectNumber.

The Process I would like to create is:

1. accounts get a project setup form.  A process outside of sharePoint is followed, three things come out of this

  a. A projectName which is a string

  b. A projectNumber which is a number

  c. The project resources which are people

2. now I would like an automated process that creates a site and can pass a. and b. onto the page. EG places the text into a content editor webpart as the first line of text........

Is this possible?  Another objective is to use Content Organizer to have documents routed into this site based on a rule that recognizes the project name and or the number.   Any suggestions on how to achieve this would be very much appreciated?

Thank you in advance
