What types should a beginner breed with first?

[C&H Exotic Morphs]

Yeah thats great advice and I have started doing that. I think I figured out what I want:
Male Pastel
Female Pastel
Female Spider
Female Mojave
Female Pinstripe

These should produce a wide spectrum of good morphs.

This isn't a bad list of females to start with but since you have a $2000 budget I would upgrade the females to 2 gene girls. And as others have stated you don't need a male right now since you are buying hatchling females.
If I was you this is what I would get.

Female Super Pastel
Female Spinner
Female Black Pewter
And then something like a Female Hypo or Fire.

Then start saving again for a nice male in a year or so.
Once you have these females started and getting close to breeding size find a nice Mojave Lesser BEL or even a Pastel Mojave Lesser BEL male.
This would really open up the doors to producing a large variety of nicer and higher end babies!
