To make 10mb--total, for 58 images, that means he has to get them down to an average of 172.5KB. KILOBYTES, not MB.
The degradation will be real. We just took a run at a job like this, and I had to tell the customer that the quality he wanted could not be done, not for under 100kb per. It just couldn't.
Let's see, 10mb. Is that NetGalley?

If you reduce the images in size if they are large enough and then lossless compress plus if there are fonts and you subset them, that's going to be as small as possible unless the images are not JPG. Then converting to JPHG and lossless compress will be as small as possible.
I doubted that the ePub would get down to 10MB in size. That my I said to deal.
One other thing I thought of that would help some. If the images are grayscale but using a 24-bit palette, setting to grayscale will reduce a the size a little.
