I've heard of an exploit that should suit you pretty well. First, you get Shadowmere by playing through the Dark Brotherhood quest line. Then, you make sure you're in an area away from anyone else that might randomly wander in and attack or other react negatively to you casting spells, shooting arrows, etc. Next, you'll want to whittle down Shadowmere's health as much as you can, but MAKE SURE you don't kill her/him. Then, wait an hour to give Shadowmere's health a chance to refill, as well as letting your mana and fatigue refill. As for archery, use cheap arrows since you won't be able to retrieve them. Wash, rinse, and repeat.
