Hireable Npcs

Hi all Im new to the shard. But I just wanted to know why are the Paladin npcs so pricy. I only start with 500 gp and to hire one is like 136 or something like that. How long are they hired for? Is it a uo day or an actual earth day? Thx

100 gp is pricey? ok. but no one uo day is like an hour or something.

I think its every minute in UO is 5 seconds real time, but the hireables are bugged and don't really charge more then once anyways. :/
