Bookcover from PSD to Illustrator and more formats

I have the bookcover in psd format. Problem is when I resize the text fades out and nothing can be read. I need some one to take the bookcover psd file and convert it to a format that keeps the formatting when I change size. I need you to give the files to me in several formats in styles such as pdf, jpeg, tiff, ico, png ai I have to give you the sizes later. I know I need sizes for [login to view URL], barnes and noble and ibook. I'm attaching the pdf file i have. Please do not do any work until I accept our bid. I'm only attaching the file so you can see the file you will be working with.
