This has counters for facebook

And for tweeter you can try out the html snippets on this page

http://twittercounter.com/pages/buttons...

Use the html block to put them in. If after putting an html snippet on a page render your edit button unavailable go to your sitemap click on the page with the html, and than click versions. Select the version before you added the snippet, and select approve from select box. Than select the html snippet page, and select delete from select box.

Chances that html snippet conflicts is about 1 in 100 in my experience.
