StackScripts or other setup scripts for money

I'm looking for someone who knows how to script the setup of a linux box. StackScripts are convenient, but if you can provide a solution that is even better (portable), that would be great.

Also, I know what I need right now, but I'm certain that I'll need more setup scripts, advice, and maintenance.

Right now, I have 80% of a relatively simple setup scripted by copying and combining existing examples, but I'm not yet adept with sed enough to rewrite service and application configuration files. I imagine that I'll often have this scenario occur, where I get most of it done, but need someone with bash, sed, python or other expertise to complete the solution and have a robust setup script.

If you got the skills and time and are interested, let's negotiate.
