Do you want to play at a showcase festival and get paid for doing so, even if it is just a small amount? If I add accommodation and food? And The chance to be seen by industry people?

If no, showcases are not for you. You want real paid tours. You want full booked rooms all over the world in the capacity of 500 people on each show.

The problem is that you actually do not draw that kind of audience and you have not the money for killing PR to get to that.

Why hell are you turning the first offer down? You just said no to pretty good opportunity?

A mistake like this will probably end your career. The hill down always starts with a no.
