upgrade word press website

I have a cleaning company and i want to make some improvements to our website and business processes. I want to automate our business with online booking/payment and hiring/screening workers. Our cleaners would be able to receive alerts. We have issue with attracting cleaning talent and building on our 5 star reputation. I found a similar website that has the tools we would like to add. I would like to learn in time how to manage the site and add video/streaming content Our website is called rightnowcleaners.ca. It looks dated and needs better pricing options to simply to for clients.
