That tool is great for reports, but like you said, you can't do it without premium version. I am sure there was a service launched here recently that was providing some sort of website audit, but I cant find it now. You could take a look in the marketplace.
Also, Moz for example will do a basic on-page report, or you could possibly post here in the hire a freelancer section and see if someone can produce a report for you - either with a specific tool or just manually.
Or you could do it yourself - you can then draw on a few different areas - on-page, offpage, conversion optimization etc. You can probably find free templates online for this sort of stuff as well.
