HELP... My first bikini wax!! WOMEN ONLY !!? - how much are bikini waxes roughly

Hey im 15 and Im in for 2 weeks before the holiday, and instant messaging will be in costume especially because I love swimming and sunbathing, micky My mother always told me I should take my shorts, because I always wear pants on the bottom of my bikini or swimsuit, I would too, but I do not really, because if I shave as long as there is anyone who has experienced before and so really painful itching. . so I like the bikini line disappeared. I do not want my mother to accompany me, because I feel more comfortable when doing it just me and the person.
This could mean that I have on reserve.
Do for those of you who had to be before you, before you wax. ?
Is it better if you have a bikini wax for long hair or short hair?
And how long will it take for the redness and pain goes down?
And one more question, how much does it cost?
Thank you for your help: D
