1) http://www.websitegrader.com. Free and does a decent job. You can then copy and past the results into a word doc. Edit the word doc to remove all references to hubpages, add your info, your logo, then turn it into a pdf. Send to client. Very professional and free.
2) http://www.freeseoreport.com. First report is free, after that there is a small monthly charge. I've only used the free version and it looks pretty good. Geared more towards seo. Allows you to add your own logo for branding.
3) http://www.woorank.com. Again very professional. I haven't used it but it looks terrific. Kind of expensive however.
4) http://www.analysisgenerator.com. Pretty good, script installs on your own server. Has email integrated into it so you can automatically send it to prospect.
