Depends on which part of Persia you're talking about... I'm assuming it the capital (it's name is fleeing my mind), so try looking it up. The land should be somewhat similar to what it used to be. If you're really interested in researching, trying finding some books at the library on ancient cultures. Look into their art, beliefs, clothing, class systems, ect. If you'd prefer doing everything online, just Google it. I'm sure you'll get lots of options!
Consider this, we'll give what information we have, here on HW, but think of the fun you'll have exploring on your own! I bet you'll find loads of cool things that someone else might find insignificant, but works perfectly for you. So, I'll try to find some time to check into ancient Persia (Mmm, finals, we'll see 'bout that 

) and you do the same, meet back here and we'll compare notes
