Really nice one, actually. It's a cross-dresser too; works very nice as a coined word, but is also an acronym with many uses, and is also a less-common last name.
I tried it out on search engines and came up with a lot of very varied end users; as a last name you should easily get low x,xxx if you approach all the Hulf's you can find email addresses for. As a coined word you might get low to high xxx, same price if used as an easily pronouncible LLLL, and as an acronym you might get high xxx or low x,xxx from the right company.
