I'd say to Blue, that if you go for the promotion to the touring circuit, you may be lucky to be able to schedule other work in your downtime from the new band. Finding something to slot into in that downtime may not be easy. Apart from that, I'd say, if you have made some contacts in that world, the thing to do is ask them if there is anything going.
Very best of luck.
I am aware of a bassist job coming up with a known UK tribute band that I would have been well suited for, but they are apparently not making the money they could, which is why the current bassist is going. Funnily enough, I turned down the opportunity to join the actual band they are a tribute to, as the money for the hired hands didn't match that of my day job at the time.
