It all Depends, there's several things to take into consideration when it comes to how much your going to charge :
Expertise
Travel
Inventory
Time
Geography
#of Services
All of these things add up and by not charging what your worth is a shame. You Want Clients Who Know Your Worth!
I work hard to keep up with the latest, and greatest, I went to school to specialize in these fields and I have won in competitions, so you better believe I will charge what I believe I am worth based on that. (I am not even nearly as expensive as most either)
I Live in Texas and I am a Licensed Cosmetologist/Bridal Hair and Makeup Artist, I travel to my clients Venue, Home or Hotel, I do add additional travel expenses (gas) outside of the 50 mile radius, my price for Bridal Hair Design and Airbrush Makeup+Traditional Package is $225.00 for the Bride, I have a set rate for MOH and rest of Bridal Party but I am definitely flexible in all my Prices.
but in saying that, I save my clients the hassle of traveling in this God Awful Heat/Massive Humidity which can ruin anyone's Perfect Hair and Makeup, I don't care what products you use, its expensive and a waste to witness your bride and her wedding party fall apart after all that work. If a Bride wants to be a DIY then she needs to be at the venue when she does it here in TX, its just too humid to be moving about from location to location, even from a Hair salon and back home then to venue for it to stay fresh without caking it on through out the day, thinking touch-up are good when traveling in this climate is a Big mistake. I do stay with my Bride up until she walks the isle (she should always be the last service to maintain freshness) and sometimes I will even wait until service is over for a reception refresher.
