Sort of raffle thing interest check / help?

I've never ran a raffle of any sort before, but I'm seeing a lot of them around and they look fun. Tomorrow I'll be giving 5 of my pups aging crystals and breeding them off to my stud the day after (or perhaps spending some GC to breed them to a leaderboard stud, or a high marking merle, or whatever people would prefer). I expect to see some decent pups from them but I'm not sure I'll be keeping any of them for my own breeding project yet simply because I already have a solid amount of wolves I've spent many GC on anticipating them as my breeding females. 

So my THOUGHTS, are holding a raffle before the females are impregnated(or after? idk) and then raffling off the pups in order of their birth. Assuming 2-5 pups a litter(average) that's anywhere from 10-25 babies. It would be blind and not an auction, you'd go in it knowing that depending on how RNG swings that you might get a T1 base or a T2 base, solid marking or not, highest stat or runt, etc. 

I considered maybe breeding them first, scrying the pups, and only opening as many slots as there *are* pups so that everyone is guaranteed a pup. Though I'm worried that if there's low interest that I won't be able to fill all the slots before the pups are born and things will go a little wacky. As well wondering if it's best to maybe choose a few good studs as options and allow the people involved in the raffle to vote? Though I'd likely need to raise the cost of entry for that because if I'm breeding 5 females to a 40g stud, then I'm most definitely losing money if I cap myself at 25 participants at 1g each. If I breed to my own stud people might be less interested, but then I can make it much cheaper as I don't need to pay his stud fee. 

If anyone has any advice I'd greatly appreciate it!

Also, here are the ladies quick summaries:

wolvden.com Auburn II | 10 Markings (notable: doubloon merle, brown merle patches) | 354

wolvden.com Russet II | 10 Markings (all markings RMA exclusive, combo, or custom including Ducat Shaded) | 352

wolvden.com Biotite II |  10 Markings (3 combos, tamaskan, and a husky) | 330 

wolvden.com Russet II | 10 Markings (doubloon husky, ducat tamaskan, cream butcher) | 325

wolvden.com Pale II | 10 Markings ( 5 combos, inuit, tamskan) | 279

Is it worth it? Will it be too much work? Will I lose out on too much money? Should I just breed them and sell the pups the old fashioned way instead?
