Generally a technician is a maintenance position, so I'm confused with you saying that you plan to pursue maintenance eventually. Do you have some of the job specs?
1. Apprentice pay is generally in the mid $20 to mid $30/hr range but to get specific google is probably your friend as MMM mentioned.
2. Journeyman pay can probably be found the same way.
3. Depending on location it can be from 2 years to 4 years.
Some of this info, if not all should be available from your counselor if they are proficient at their job.
