I need someone to write a simple piece of software that will allow me to manage my spa. I need a Appointment calender that can sync to a calender in wordpress. I also need to be able to keep track of my inventory of products. I also need to be able to add services such as massage and pricing for the services so i can keep track of what services and products we sell. I need something very simple, nothing complex at all. The website the calender will sync to will be a wordpress website.
