Attention Photographers

I wasn't going to book yet because my wedding so far away....however I am having some difficulty getting my engagement pics done. Some of the ladies Online have told me that their engagement pics are included in the wedding packages....So what I need to know from all the photo people how much of a deposit I would need. If not how much are you charging for just the engagement pics???? I need at least 75 pics for the announcements. Thank you so much everyone
