Build Builder - cause I am lazy

Hi all,

I am new to TeamCity.  I have a massive number of TC builds to setup.  I was going to setup a build builder.  This would be a build in TC that created other TC builds given some paramters at build time:

1. Create SVN branches
2. Create SVN drift reports
3. Provision web site for staging this branch
4. Provision 4 team city builds
     1. Development loop
     2. QA/Code complete build.
     3. Staging build
     4. Production build
5. Provision a project in my defect tracker.

Question:  How do I script TC or make REST/WebServices calls to automate the TC portion of the outlined provisioning?

Thanks
-Jonathan
