Get your females first. The males only need a year, and chances are prices may be slightly lower on males in 2 years, so you'll save money there.
Morph females are always a great investment. Starting off buying the males doesn't really make a whole lot of sense if breeding is your only focus.
Moreover, its not easy to find breedable adult females. No reputable breeder would part with their breeder girls (they are worth their weight in gold) and if you do find someone willing to sell one, chances are 1) you'll pay out the wazoo for her or 2) Its a girl that has thrown duds or never laid at all or some other issue that makes them not worth keeping.
*edit
Did you mean that you have those males already or that's what you wanted to start with? Sorry for the confusion...
