Hair Salon booking System

I am looking for a booking software system for a hair salon. They have 3 stylists in one salon and 3 in another.

The booking system need to take customers contact details, be able to email out newsletters and text reminders and allow the customer to book an appointment with a calendar system online.

Please can you send me an example of the software you are proposing and the total cost to add this to the current website which is using WordPress?

Thank you

Grant
