Etiquette question

Buying a fursuit head base, and then taking a commission to fur it to a person's specifications. Acceptable?

I see a lot of people buy head bases, fur them, and then resell them. That seems to be generally okay. I'm wondering if it's acceptable to purchase a head base, and then sell the right to have it furred to a person's specifications.
