No, 3 months is not a long time in general. I've known guys who took much longer than that to get a decent band together.
My classic rock group came together lightening quick. I was referred to the drummer the 2nd week of August in 2006, we hooked up with the guitar player the following week, cut our first studio demo on August 29th, played our first gig Labor Day weekend, and by the start of October we were gigging 6-8 times a month
But we're all very experienced (in other words, old

) and we have a ton of contacts, so getting gigs has been easy for us. And we are a cover band of '60's, '70's, and '80's tunes, so it's not brain surgury.
My funk/fusion band has taken longer to get cooking, minimum 3 months of weekly rehearsals before we booked the first gig, and it's hard getting much more than 1 job a month. But all of the guys work in other bands, so there isn't as much pressure to book new work ......
