Looking for Photoshop help

Here's the deal.  Kelly has prints of her work that she sells online.  One of the contacts she has made through her blog has a business creating cross-stitch patterns from artist's work. (See here) She has contacted Kelly about using her work as potential patterns. The problem is that in Kelly's photos you can see quite a bit of the canvas texture.  The goal is to minimize the texture and potentially smooth some of the edges/textures/etc, without compromising the detail or sharpness.

I included just some low resolution thumbnails of potential photos, just for reference.

If you think this is something you can do, let me know. I'd like a prospective time frame (ie- a week, 3 days, a month, whatever) and a potential cost.  I don't anticipate this is too tough for someone with the knowledge and software, we just don't have either.

Thanks in advance.
