Artwork/Graphics for Product Label Resized

I have a 2 x .psd file containing 2 types of product label - however, they will not seem to resize and preserve the aspect ratio? In addition, I have also added further information (usage instructions) to ONE of the original designs and have a bitmap image which I can convert into any standard image format (jpg/tff etc.) so that the design/information/layout/ etc. can be seen. I will possibly want some revisions made to this original label though. The project: 1) Make any changes requested to the original label 2) Add the same information to the 2nd product label 3) Provide proofs of both labels 4) Carry out any amendments to proof as required 5) Produce HIGH RESOLUTION - print ready (1440dpi) quality colour artwork for BOTH designs which can be resized - keeping the original aspect ratios OR provide 6 separate files of artwork in the sizes I require (up to a maximum of 8cm high x 24cm long) I don't know how to use photoshop but the printers have said they will accept files in .psd, jpg,tiff It is important that the COLOURING of the product label remains the same as the samples provided This is a small project for someone who knows what they're doing so please price your bids accordingly I will want to see examples of the winning bidders previous work I would like everything completed in 7 days - maximum Payment in 2 stages 50% at start and 50% upon successful completion.
