You have no plan in this move. You have no potential job in place. You hope you would be able to be hired once you are in your new city.

You and your friends might consider going on line to seek employment. There are many web sites where you might apply for many jobs, prior to you moving.
Once you have found several of these sites you would be required to complete some basic information, followed by down loading your resume.

In some instances, you are able to set up an interview using one of the many visual communication sights currently available.
