Show I see a tax accountant or should I just e-file my taxes?

I'm 22 years old and for the first time in my life I will not be counted as a dependent upon my parents tax forms. I have always had a job so for the last 5 years I have been doing H&R Block e-files. This year I will make money from 2 jobs (totaling around 12k) and I will also be receiving a little income from stocks and interest. My question is should I continue using the e-file method or go and see a accountant? E-file is simple enough to use but if I see an accountant, I have the feeling they will be able to find all those loopholes and things of that nature that will maximize my tax return, will this be true? Also, I moved from a state that didn't have a state income tax to one that does, so that will be one more set of paperwork that I will have to deal with that I am not familiar with. What should I do in this situation? Thanks in advance!!
