Your best bet is to get the base co-dominant and dominant morphs. To be honest I started with 5k to invest and it wasn't nearly enough. Your going to get a bunch of hets anyway and will be limited to how much you will be able to breed if you breed everything to a single normal male. Males I would get are a Spider, Pastel, Mojave, and Pinstripe. Then get a bunch of normal females, see if you get normal males and morph females you can only breed the morph once per season but if you get male morphs and alot of normal females you can breed twice as much assuming you have enough normal females. Either way I still say start small because either way unless you buy breedable male morphs (alot more money) you'll have to wait 2 years (or one if you decide to try and breed a male at 500g or so) to even breed your morphs, all your females would have to be old enough to breed though.
PS: Let's not forget hemi-peen infections, don't over breed your males or you'll be in trouble 2 or maybe 3 females in a cycling rotation max.
