There have been several places in recent Beth games where you can call, summon, or hire temporary help to aid you in a tough fight. In OBlivion you could bring along an apprentice mage once you reached a high rank in the mage's guild. In FO:NV you could use a radio item to call for some NCR troopers to come give you a hand. I'm sure there will be something liek this in TES V. It may, however, only be available at then end of quest or something like that which might limit access for low level characters.
On the other hand, i can understand that you might want some help if you're anticipating a diffcult battle ahead, but be honest, do you really want to hire a body guard if you're just out exploring the countryside? Besides, you're the Dragon Born, people might think you're a wimp, and then where will you be, just some guy who does funny shouts and then has other people kill dragons for him.
If you are really aren't the fighting type and are just dying to have a companion who will go with you anyhere and never complain and always be ready to help you in a fight, then I suggest practicing your conguration magic.
