Have you did the side quest in Bravil (I think it is, the same town where the abbey is), you come across an old guy in the wee bar not the fancy one, he asks you to help his sons protect the farm, complete this quest without either son dying and he gives you a fairly useful enchanted sword.
Alternatively, if you have completed the mages guild recommendations and can access the mages guild university, in one of the buildings you can enchant items by using enchanted soul gems, just make sure you have the ability to use some spless such as fire attacks etc, and you can enchant a sword or whatever weapon you prefer with this type of attack.
Another way is to murder someone without getting caught, when you do the first task for the Dark Brotherhood you will be given a weapon, initially it's not enchanted and not very strong in attack but as a last resort it can be used against ghost etc.
I always find fighting the goblins the hardest they are a total pain, wander around the world find caves and forts etc and you can pick up a lot of useful items.
