Wedding photography costs $600 to $1000 over here, the equipment is typically 4 to 8 years old and costs about $1500 (body + 24-70mm lens + flashes, MPB.com prices).
Where is over here? I’ve done a few weddings back in the day, the lenses I’d use (24-70 f/2.8 and 70-200 f/2.8) each cost over $2000 new in today’s US dollars… Then you have backup lenses, backup SLRs, etc. (but I’d usually borrow gear (still pro gear) as backup from people I knew which made things a bit cheaper, and I’d lend stuff to them when they needed)
