How much is a bigger avatar like Uncle's?

Afaik, you either need to be a staff or pay exorbitant amount of tc for that

That is correct. I asked Uncle how he got his avatar that big and he told me he bought it, yet that it was also expensive. I would assume you would be able to pm any admin/smod (users with a bolder red/blue names) and they woul have more information about it available for you.
