I like your plan to produce 100(ish) BRB's a year as supplemental vacation income. I do have a few questions / points for you.
Looks like your sig file is out of date because you said you were building a breeding group and will start breeding next year. The sig file has 0.1 BRB and last time I checked, that won't produce anything but poop in the cage. 
If I were you, I'd rethink the "holding back most if not all of the babies" plan. IMO, you'd be better off purchasing some diverse stock. By all means hold back any outstanding babies, but don't let your colony get too inbred.
To produce 100 babies is anywhere from 3 huge to 10 small litters. I just checked my records and the average litter is 17.45 babies. So to average 100 babies would mean around 5 or 6 litters per year. Even kept in pairs, that's only 12 adult BRB's, less than one litter.
Another option would be to breed females every other year for larger litters. You could still do the 12 BRB's but make it 4.8, that woulod be only 4 litters pewr year but with larger average litters should still be around 100 babies per year.
>>Being mainly a Ball Python man, and have been for years before the huge increase of morphs, I was initially surprised by the decrease of prices last year. But if you think about it, there is not other boid that is kept in numbers even close to what bp's are. It's fairly easy to get a decent size breeding group together and these snakes aren't hard to breed. It is very easy for someone with basic snake care experience to produce 50 or more babies if they want to spend the money on buying alot of former pet females.

>>with that said, lol. I've been slowly building up a group of BRB's and from all the research I've done, they seem to require much more experience from the keeper to get consistant results when breeding. Next year will be the first year we breed our rainbow's over here and will be holding back most if not all of the babies mainly because out of all our snakes, wild type rainbows are second only to hypo rainbow's, lol. SHHHHHHHH don't tell the ball python forum I said that, lol. Eventually I want to be producing about 100 ball pythons a year and 100 rainbow's a year mainly as a supplemental income to pay for our yearly vacation to daytona in aug and hopefully save some. No neither me nor my wife will ever quit our day job's as nurses and we don't NEED the extra income but it is nice. who wouldn't rather make $175k a year rather than $150k. So with me, I have snakes beause I love working with them. I have so many to make a little money doing what I love.
