What I would do would be get a male pied and a codom het pied(pastel, lesser, spider ect..) and/or some het females for your pied project say $3000.
I would get a male clown and a codom het clown and/or het clown females for a clown project say $3000 also
and with the remaining $4000 Get a queen bee or similar 3 gene male and some large normals, maybe pastels and some base morph females(fire, enchi, mojave, what ever you like).

You can breed your specific projects (pieds, pastel pieds, clowns, pastel clowns). Then use your 3 gene male queen bee to your big normal females and base morph females when up to size. You can also work your queen bee into those pied and clown projects as well as using your pied and clown males to your other codom females. You could replace clown project with another codom project of your choice if you didn't want to go with a lot of hets...

just my 2 cents..
