Is it possible to request custom orders from Peterbot or similar shops?

A few friends and I are planning a funny jersey for tournaments, and we’re looking for a clean blank jersey that we can customize ourselves with memes and inside jokes. The idea would be to order one of their jerseys, but without any logos or branding on it.

Does anyone have experience with requests like this? Is something like that usually possible?
