A Few Creatives for an 18+ Site

I'm looking to get a few creatives done. They are for an 18+ website featuring gory content. The creatives would include: 1 x small resolution animated gif of a woman on a spit roasting over a fire 1 x static site icon of a woman on a spit roasted over a fire (512px square) 3 x static header images with graphic motives (1200 × 280 pixels) 1 x static "donate by bitcoin" banner with a graphic motive (840 x 200 pixels) I'd prefer a provider able to provide mock ups and maintain confidentiality.
