they want the letters MLA to stand out with the rest of the company name beside the letters
What does "stand out with" mean?
How can anyone advise you on a typeface for MLA that will work in some way relative to "the rest of the company name", if you don't show "the rest of the company name"?
Logically, your question amounts to "What typeface should I use to make MLA stand out with something?"
Yes, you have 2000+ fonts. You also have the internet...
Short of designing the logo for you, choosing a font is a little premature. As previously suggested, there simply is not enough information for anyone to be able to make a solid recommendation. If you've met with the client you probably took some notes and got an idea of what they are looking for. So, you're in a better situation to recommend a font than anyone else. The logos I selected are pretty basic, but they emphasize the letters M-L-A while also including the full name of the organization. This is design 101.
And another thing. Since you don't like anything in your computer, check out some font foundries...
it's a good resource to look for something you don't have on your computer. You could go to your local bookstore and look through some logo design books and some typography books to get some ideas. Then, sketch out a few comps using some different fonts. If you develop something that you think the client will like, buy that font. You're a designer, you should know all this stuff already.
