Not to discourage you, but I have to agree with Lance. Even if you want larger plants, if you know what the parents are, and what they look like, you can get some great plants and often for less than divisions will cost.
For example, when I first got serious, I bought a younger plant (though nbs) of rothschildianum 'Rex' x 'Mont Millais' (one of the best roths!) for around $100. A division of the awarded plant would have cost me MUCH MUCH more. Thousands, at least.
Because I know the parentage, I can afford to pay less and yet be assured I will have a pretty good plant. At a price I can afford.
Divisions in the paph world, at least among hobbyists, I think are tricky. They are really directed at the collector market. If you are just starting, we can help you find what you like and it might not be so highly priced.
It really depends on what you might want to acquire.
So let us know, and ask questions. Maybe we can help!
