If I was in a band and someone wanted to charge me, I would want a mix and mastered copy of the performance from something like the soundboard. otherwise, if we're just talking a two audience channels, I would do it myself and not pay somebody.
I'm pretty sure all first times are amateur so just come to realize that it will take practice to perfect this.
I agree. I've been in several bands, and when I wanted a show recorded I did it myself.. however, you'd be suprised how many people want a live recording and are willing to pay for it. I already have 4 bands asking me to do their show and I haven't even started yet. For $50/$75 bucks a pop, it's worth it to them. Most simply don't have the right equipment, don't have a person to do it for them, and don't care about running through the soundboard. I don't plan on running through the soundboard, because then you have to start working with the venue - and I'm not going that route. Plus you don't get a "live" feel.. and mics will do a decent enough job to capture a performance.
I've been writing music for 10 years, playing music for 16, and recording music for 8.. Field recorders, however, aren't my forte, but it's not too much different. There's just too damn many of them.
There's a large local scene here, and many would love to have someone record their stuff with video, to toss up on youtube
