calculator , booking , cheeking.for moving co.

Hi everyone. For a small moving company we need ( CUSTOM CALCULATOR) , a system(BOOK YOU MOVE ONLINE) that allows users to request an estimate and that estimate would be saved to a database. Then we need (CHEEK YOUR MOVING STATUS ONLINE) to be able to access all of the requests and approve, update or decline the estimate and the system would send an email to the user when we update the status with the details. There would also need to be an interface where users could enter a confirmation number on our website to query the database and check their order.
