Image Magick Script

I have a flash application that outputs multiple JPEG Images. I need someone with experience with Image Magick to do the following: 1) Check Each Image wheter it's RGB or CMYK 2) If an image is RGB convert it to CMYK JPG, if it is a CMYK image leave it as is. 3) Compile all images in the order provided from the flash application into one 300 DPI CMYK PDF, and one 72 DPI RGB JPEG image. Need this done ASAP. Please point to some projects you've done, especially something with image magick used. Please provide a date you will actually be able to deliver by. Thanks.
