Graphics Changes - Create Banners From Existing Graphics

I've had a website header and ebook cover designed and I now need matching banners created, based on the current header and card design - the current graphics files will be provided to the winning bidder to work from. Banners required (size in px): 1 x 468w x 60h 1 x 120w x 600h 1 x 200w x 200h 1 x 728w x 90h 1 x 300w x 250h All files will need to be provided in jpeg format. Please note, completely new designs are not needed, all that's needed is for the existing header/ebook design to be modified in a way that it will 'fit' into the above sizes & a small amount of text to be added to each banner (something like 'Click here now' etc.).
