Can you assist with App creations for mobile phones

Hello, Could you please assist and provide information on having an App created for a mobile phone. 1. What information do you require from me? 2. What is the estimated delivery of App completion? 3. How does your pricing work? 4. What is your payment method? 5. Do you provide after creation support? 6. Do you have a template which you send out for me to complete so to gather information you require to provide a quote? 7. Are ones ideas kept confidential?

Kind regards Cindy
