While you can get a werewolf or vampire bite at any level you must complete the quest within a short time period or else you lose the bite. The quest may be completed at any level, however the NPC's are roughly level 40, so if you're new to the game or have troubles abusing AI intelligence you might find it challenging to complete at an early level.
I've got two V14's and around level 15 on my 3rd char (a sorc) I got a vamp bite, while I was able to defeat the 10 assassins in the quest to complete my vampire transformation it was still challenging, mostly because your attacks AND spells miss a ton! I definitely died quite a few times trying to complete.
Again, if you're new I'd recommend getting to level 30 to make it less frustrating
Unfortunately though as I'm a PC player I can't assist in giving you a bite, sorry.

The werewolf quest is easy. I did it the other day at level 11, no problems, could have probably done it earlier. Just keep moving around the mammoth to avoid its attacks.
You still have to get to the last zone of your faction, because the bite must be done at the WW shrine. You also have to do a quest which will have level 40ish mobs.
