Ok... my heart hurts now so I gotta be business like...
The fact that you have a male Lesser is good. If you have any normal females, great, get them big enough to breed the Lesser to. Keep the girls... in time buy a Super Lesser BEL to breed them to.
If you can afford it, buy a male Het Lavender Albino NOW. Breed them to normal females, keep the 50% het females. A year or two before those 50% Het females are ready to breed, buy a Lavender Albino male, or two, depending on how many 50% Het females you have. Breed them like crazy, and by 2014 you can pay for the lil nephew's college education, and then some.
