OK, let me break this down... I see two parts to this...
Part 1, you say "I want to add feature xyz"
Part 2, you show the source
What's missing from part 1, is the work you've done to design the feature, its api and how you will invoke it from your code...
I'm not totally understanding yet what you're asking for... do you want help on a specific part of openacs you're not understanding? Or, do you want someone to literally do the work of building the site?
If you want to understand one specific piece, what is it?
If you want someone to come onboard to help you build the site, there is a lot of talent here that can help you, and suitable arrangements can be made, assuming you want to go in that direction.
