Greetings. I need a mockup as soon as possible. Paid options are okay with me as well, just please, not too expensive.

No worries, the help has arrived. And yes, it gets increasingly difficult just to find good stuff on the internet, too much noise and ads. It is especially true when it comes to quality mockups. But I will recommend this platform where you can download the Magazine Mockup you seek. Even the free options are great there, and the paid options are not expensive. So I believe it should work for you. Good luck.
