It all depends on what the going rate is in your area. Since you're "green" you have to charge less to make yourself more appealing... I'd say maybe 60% of what the pros charge. (:
I love photography. The second I can afford a decent camera I'm going to live behind that lens lol
It varies by region I think. My cousin got married in a different state and paid almost $800. My sister got married here and paid around $500.
Just make sure you're getting what you think your time is worth (:
Just tell them that Awesome doesn't come cheap :p
No problem. Hopefully it turns out to be good advice lol
