Dress Maker - Immediate!

My MOH has requested to wear a pant suit instead of a gown because she has a prosthesis on her leg. So, I found the perfect suit for her at Ann Taylor the other day except it's not the right color or size and my wedding is not for over a year so I think we should wait a while before getting something made to fit her (she might go to weight watchers). However, I want a pattern to be made from this suit (I bought it for this reason but have to bring it back). Can anyone do this for me? If you make the pattern I will use you at a later date to actually make the suit as well. I need to do this quickly though - I want to bring the suit back this weekend!
Thanks!
