Scott,

I suggest that you take a look at the services provided by Lightbox Inc. Bruce did a splendid unsharp mask for one of my 4x5's. My experience with them was very positive and I feel they take a great deal of pride in their work. Bruce has taken the Howard Bond workshop and they even have a gallery of Bond's work up. Best of all, the price was very resonable -$40 for the completed mask. I am not affiliated with them in any way, I'm just a happy customer. Here is a link to their site, click on fine art services. Cheers!
