Where can I find many 32px avatars in the same style?

Question

PHP

We need a large set of avatars (at least 50 pieces), drawn in the same style, 32px in size.
Paid collections are also suitable. A generator is also suitable, but avatars should be of high quality. I like this 8biticon.com/, but the size is not the same (20 by 20 pixels).
I also found such a set, but there are few icons and at 32 by 32 they look too small.
