I recently job searched from 500 miles away. I used linkedin, glass door, indeed, and a few industry specific websites. I applied and booked interviews in waves, so each trip for interviews included 2-3 companies. The last bunch that I did and got hired from, I applied, came down for interviews a week later, and had to be in town and ready to start in 16 days. If you are certain you are moving, you should start boxing up things you don't need I used Uship to get all the boxes moved and put in a storage locker in the town, so when I moved it was a quick trip to the storage locker to get that stuff and the rest was shipped down to me or I bought new. Good luck.
