Need an app to book a service based on location and time and selecting few other parameters. We run an e-waste recycling company. Our customers need to book our service for a particular timeslot. They should later be able to track the pickup and should also be able to view the details of previous orders. Payments are handled offline as of now but might be added in time. Looking for someone who can be committed to the project for a long term basis, available for revisions and improvements when necessary.
