App Designer and Developer for Cleaning Business

I am looking for an experienced app designer and developer to create a custom app for my cleaning business. The app should be designed and developed for the iOS platform and should allow both customers and employees to access it. The app needs to include appointment booking functionality, allowing customers to quickly book an appointment and check service availability. The app should also securely handle payment processing and allow me to make data-driven decisions through reporting. Being a business-critical project, I need someone who is reliable and can complete the app on schedule and within the agreed-upon budget. If you think you have the skills and experience that I need, then I look forward to receiving your proposals.
