Like many, I didn't like having to join the mages guild, and complete all the initiation quests, just to make a few basic spells. 
However I also thought that the mods which give free access to the service detracted from guild membership. 
This is my attempt at a balance.
This mod adds a 'public spellmaking office' just inside the arcane university. 
Here you will find a helpful mage who will make any spell for you, assuming you can afford the triple gold cost. 
Upon initiating 'Spell Making' topic, you are given an effects spell, giving access to all available spell effects.
All your magic skills are set to 50, thus allowing the creation of any spell, journeyman level or below. 
The effects spell and skills are returned within a few seconds of returning to game mode.
