1) Figure out your price range.
2) Get your teacher's advice on bows
3) Do a research on bows in that price range using the search function on TB.
4) If you don't know how to play with a bow, they will pretty much all seem similar. It's hard to tell a good one from a bad one until you have had maybe a year or more of practice using one to develop sufficient skill to where the bow quality is a limitation.
5) A good strategy may be to buy a relatively inexpensive CF bow (like Shen Ophelia, Finale, the better Yita's etc.) and use it until you are skilled at bowing enough to have a preference.
6) All due respect to Hdiddy, but pulling a bow across the string looking for the best sound/least effort will tell you more about the hair and rosin than the bow itself. Hair and rosin are both consumables that will be replaced several times over a bows life (like strings.) Bows are generally judged by balance and bounce (the elasticity of the stick) which facilitates bowing technique that you will later learn but have no way of judging now.
7) Check out the Finale demo on the Jason Heath blog, Andrew Anderson and bassius videos on YouTube to become more bow literate.
Good luck
