Yes, especially if you need it for mass printing [usually you need the pages to bleed - i.e. you have to make it slightly bigger so that at the printers they can cut better].
Also, you could use Photoshop, I have seen some great stuff with MS Word...whatever you are most comfortable with if its not your bread/butter...
Also, consider outsourcing it...there are great designers here, Im sure you could find a decent one @ fiverr...it might save u a lot of hassle
