Welcome, Queen of Chaos
There are several good fonts available for elvish writing - but also several less good and incorrect ones.
You'll find most ones on www.dafont.com (here the direct link to the section with the elvish writings:
http://www.dafont.com/en/theme.php?cat=605)
Most fonts there aren't really the best, but they have all of Dan Smith's fonts - those are in my opinion the best ones available, though their use is very complicated and you need to know how the elvish writing systems works quite well
(for the eight-eleven-thing I used the most popular Dansmith-font, called "Tengwar Parmaite"; also very useful the "Tengwar Annatar Cursive"-font).
An easier font is "Tengwar Gandalf", it directly transcribes the letters to the elvish equivalents. That works quite easily and quickly, but also brings some errors or unprecise transcriptions with it; yet I'd recommend it for simplified usage.
There are also several fonts that imitate the elegance of Tolkien's elvish alphabets, but are still recognizable as Latin letters; they look really nice, like for example the "Elven Common Speech"-font. There is also the one simply called "elvish" or so, it's kinda strange, but also doesnt look bad (I think it's this font - http://www.dafont.com/dl.php?os=win&fichier=elvish_ring_nfi)
Other Tolkien-fonts are for example "Ringbearer" (the one that looks like the filmlogo-writing) or the "Stonehenge"-font (aka "Tolkien"-font), there are several ones available on dafont.com.
