desktop website that is mobile responsive for cleaning business

Hello! Im starting a cleaning company first in my local city then later expanding. The job is developing a website for desktop and mobile friendly We are a cleaning business that have multiple cleaners, and those cleaners have there own scheduled. we want our clients to choose cleaners based off of reviews that our customers will give them once cleaning is done. what i need on the website: *built from wordpress because its simple to control the website for me * a schedule/calendar of all our workers with reviews on one page that shows when they are available *be able to put pictures of my workers *be able to use coupon/promo code at checkout *be able to pre-pay online and once the job is done we would then charge them plus give a tip *be able to automatically price based off what service and be able to add extra * i need text and email reminders a day before our cleaners appointment to us and our clients i already paid for hosting i also have a reference site as an example of everything i want. [login to view URL] I want a very rough estimate on how long it will take and the costs. just so i can get an idea. Thanks -Ryan Vasquez
