Grammar expert needed for trivia game revisions

I am looking for someone to proofread and revise grammar and writing style for our trivia game. We have a grammar guide we created.

I need someone who can follow specific directions and who will understand the style of previous releases. This initial job could lead to a lot of future work.

The initial job will be to revise 250 questions with 4 answer options each. It is NOT technical writing but rather mainstream lingo.
