The best advice I can give (which I wish I could tell me myself back when I was getting started) is to just get your females now. Get some nice single gene females. Pinstripes, Black Pastels and Lesser Platinum are always nice but it comes down to personal preference. Be very picky and looks for good examples of the morphs. Ask to see pictures of the parents so you can see how they hold their color. Any good BP breeder will be able to provide you with pictures of the parents. Also make sure the animal is a good feeder (rats!). This will save you from years of frustration.
When you girls hit around 1000g then start to look for a male. This could be a 1-2 years down the road. Take this time to research and think about what genes you want in him. The genes in the male are the most important genes in your project since his genes will be going around to all (or at least a bunch) of your females. This is also why I highly recommend saving and getting a 2 gene male such as a King Pin, Lesser Bee or Black Platinum (which I think are a really unappreciated morph). By having a two gene male you open up so many more possibility to create some truly amazing animals.
