This honestly was not in response to your post.
I didn't even see your post until after I posted the poll.
It's a question that gets asked often. Most times people will be glad to share, but to protect everyone's feelings I decided to make it an anonymous poll!
I'm sure others may PM you with info on their cost and agency info, but this will give you and others who may be interested at least a ballpark average.
Also, I feel it's very important to add that you shouldn't let cost influence who you use for an agency or attorney. Some good ones have low-average fees and some not so good ones have average-high fees. Bottom line is you can't judge an agency or an attorney by what they charge. Get lots of feed-back before deciding on an agency!
