Mobile development

I need an Android app. I would like it designed and built. I am an entrepeneur that has owned car washes among other businesses. I believe there is way to simplify and improve how car washes are managed and therefore I want to build a basic android app based crm and transactional system for the car wash business. The app must allow a car wash owner to input his price list for the types of services/washes he offers. It must have a table for customer information using vehicle registration number as the primary identifier of a customer. The app must have a transactional screen that allows the car wash manager/receptionist to input the vehicle registration number as a customer drives in to the car wash premises. This must then recall onto the screen the customers details such as name, phone number, vehicale make, colour, last visit to the car wash, how many visits he has had in the last 30 days, etc. Upon the customer choosing the type of wash he wants for the day, the screen must automatically populate the price and capture a record for this customers visit to the car wash. Once the car wash is complete, the customer must beable to pay and rate the the qualitu of the wash. This info must be captured by the manager on screen and the record for that customers visit on that day updated and completed. At the end of the day, the system must produce, a days turnover report, also showing volume of customers, quality ratings etc.
