Hello,
Sounds like a fun project. I am a native English speaker in the US, Florida to be exact. I am pretty good at documenting websites, and understanding the purpose of all components of a website. I am familiar with most web technologies, so it doesn't matter what languages used on the site.
I put 14 days as I have no idea how large the site is. If its a smaller site, then the project should take less time and cost you less money.
Ready to start when you are.
