I won't be able to make your preset, I'm just here to state something about your request.
Items cannot be included into a preset UNLESS the maker also knows how to make items.
Equip-able items and presets are extremely different from each other... the only way it CAN be done on a preset is if they draw the accessory (which we all know doesn't look as nice as an item).
Items require prior knowledge about 3D rendering, 3D texturing, and Python coding. None of which can be learned in a night.
(Trust me, I've tried :P)
Presets are just Photoshop or GIMP and a template for the textures where you fill in the blank.
