APA and MLA aren't that different. I've never used MLA so I can't help you off the top of my head, but I've been using google for the past 2 years now and it has worked well for me.
By this I mean, search google for "MLA format" and just use any of the school resources that pop up. I use MRU's (as I go there and its a really good one), but I found
Toronto's just now and it seems good. Go to page 3 on "Formatting Quotations".
