I would get females now, and wait a year to get males. Females will take a long time to breed, so you will save money by getting a couple of females now, then hatchling males next year. Prices will drop on males in that time, and they will still be able to breed when your females are ready.

Edit: I didn't see that you have breedable normals. That changes everything. Get whatever you really want the most right now. I'd probably do the breedable male pastel and a female het albino. You can produce pastels this year and buy a male albino next year.
