In my experience, a lot of bands are run by bass players... if they aren't on the gig, there isn't a gig. Sometimes, you just have to be tenacious in searching opportunities out. Networking locally is the biggest source of work, or has been for me.
The skills required... how long have you got? Excellent communication, being responsive to all forms of comms (texts, calls, emails, social media posts) and replying quickly and efficiently, having a thick skin, doing all your prep, arriving on time and being punctual and ready to go. Keeping your ears open, going the extra mile if required, keeping your gear in top condition and carry spares for everything. BVs are an added bonus, lead vox even more so. Be the dep you would want to hire.
Happy to discuss privately by PM if you want to go in depth.
