I couldn't see a shop doing this for (much) less than $350 if they do the complete job and use 1st quality u-joints at least in my area. Most shops in the NY metro area are going to be charging $100/hr labor. In any event, I'd recommend if you do the job yourself, to use your original half shafts and mark what side of the car they came off. I had mucho problemo's when I went to 3" shafts cause they were too long. Of course, I didn't see fit to measure them when I received them and only noticed they were screwed up after I put them in and the wheels were all towed in. And careful, don't bend that flange.
If you are interested in doing this yourself we sell both the axles and spicer U-Joints
