I think the OP means a smith or enchanter with a skill of 100 that we can pay a fee to use their services to smelt us a weapon, or enchant something. That way we can have a weapon with full stats, but pay instead of having the skill required. I think that if they were meant to implement it, it should be either very expensive for a merchant with a skill of 100, or there's a cap on the level of the smith. Otherwise it defeats the purpose of raising the skill.
If that is what was meant sorry for my mis interpretation, although I stand by what I said about the other aspects of the game I mentioned.
As to what the OP meant, I think it would be a good idea providing it was very expensive. Much more expensive than buying a powerful generic weapon such as a deadric Claymore for 4000 gold. If you were to have a weapon specificallymade for you to the same spec it should cost double or even treble.
Otherwise like Nightfox said there would be no point is raising the skill
