I remember years ago playing at a showcase run by an agency. All the bands set up around the walls, and one by one they went on and gave it their best shot, while a number of potential clients walked around ticking off points. Very far away from the atmosphere most of us normally play in. A real meat market. We got offered a cruise ship booking, but in the end turned it down....

The agency experimented with videos for a while. Boy do I wish I had a copy of ours. I'll never be that thin again!!!!!

but on the whole while I sympathise with us poor musicians struggling to market ourselves, we do get a lot on the plus side too and no-one's making us do it...
Cheers
