Design for Apparel & Accesorries

Looking for a designer that will be able to design creative & visual illustrations, to be used on apparel & accessories. Designs will be based on themes (collections) - Currently have about 5 different collections. Each collection would require about 5 custom graphics. Each graphic would be applied on the various apparels & accessories (the graphic basically is available in any type of product - eg: mug, tshirt) In addition to this, I would need the banners for each collection to be designed. As well as the graphics for social media. I am only looking for serious people please who have a good eye for design. And this would be an ongoing project for every new collection. Usually on a monthly or bi-monthly basis. Scope of work upon finalising project: - 5 graphics made for 5 collections each (equals 25 custom graphics) - Each graphic to be placed on demo products / mockup file - mockups required are for T-shirts, Mugs, Phone cases and pillow cases ** In some cases the mockup may be needed in various colours - eg: t-shirt - Up to 10 banners design for collection announcements, made in website slider image size + FB / Instagram sizing It's important the designer use the right guidelines that are print-ready when providing back the final files. If the initial project goes well then I would like to stick with the same designer & continue a long term relationship with them to source future work.
