That will depend on what you're looking for and how organized you are with your briefs. You'd be surprised about how many "quick requests" we receive that end up taking days just because briefs are unclear or clients go back and forth with revisions for days. Creating designs isn't the hard part, communicating clearly is.   In order for us to deliver amazing designs, our processes require at least 1 business day for all requests and revisions. However, if you've been working with us for a while and your designer is already used to working with you, provided that your brief is clear and the request isn't too complicated, they might be able to get it done within the same day. Just ask your account manager and they'll let you know if it's possible.
