Banners - design is done - needs to be created in different sizes

There are 10 shop categories that each need banners in these dimensions: 120x600px, 160x600px, 300x250px, 468x60px and 728x90px. The 10 categories are automotive parts like oils, filters, seats, tuning etc. Each banner always has the same elements: logo, call-to-action (button), one image and the brands. You might see these elements in the design file. You will get all files neatly packaged and ordered for convenience. Mainly you have to create the PSDs and arrange the files. I will need the PSDs and they will have to be neatly ordered. I need a folder inside the PSD for each category. Inside that I need more folders for call-to-action and the brands. This is really important. I'm actually looking for a designer to further outsource design jobs - and I'm not just saying that. Looking forward to hearing from you.
