I got my first airline job as a turboprop (F27) first officer 17 years ago and started on £17.5K. Things have improved in all that time to £23K!
Says it all really.

The CTC guy who assessed me at EZY was also ex 757/767 but I don't know from which operator. This was about 3 years ago. Had never failed even an item on any OPC/LPC. Had never flown a 737 up until then either.
Water under the bridge and I am far better off now than if I had gone to EZY.
Get your command with present company and get some command hours up. If you still have itchy feet then don't give up your command. I did and regretted it. I can maybe think of one or two operators it is worth giving your command up for.
All the best
