First of all, where do you plan on having the surgery? How many has the surgeon done? What is his/her success rate? Can you afford to travel? Have you explored the BCIR version of the K-Pouch? It is done in St. Pete Florida.
Could you go to the Cleveland Clinic for the standard K-pouch? You really want to choose a place that has done lots of this type of surgery.
Why do you want a K-Pouch over the J-pouch? You need to do lots of homework before you even think about when you can return to work. Or, how many days you will be in the hospital. I wish you the best. By the way, I have had a K-pouch since 1976. The J-pouch had not been 'invented' at that time. If it was available at that time, I probably would have chosen the 'J'. PM me if you'd like to talk off-line.
