After changing career, doing a degree, and have just finished a MA. Alongside that I project managed a 2 year project from start to finish with a cumulative and peeling staff of 100 (so for the most part it was supervising a few, but for about two weeks it was the full 100, then it went back down to a few again). The job I've been doing normally commands a salary of £40-50k, but I've done the whole project for experience, as it tied into my MA well, and I could use it for my dissertation.
Granted the jobs situation in my area isn't fantastic, but what would you theoretically think I should be looking at salary-wise? I can obviously give more info, but didn't want to waffle on too much.
