Hi I have read your job description.
I will deliver you an Android and iOS application by the end of 4 weeks. I propose your application can be of hybrid nature which will work both on Android and iOS. In case you wish to have an application which has native android feel, I can provide you with an android App only.
Both arrangements will cost the same. You will need to make advance payment of 50% after agreeing to work together. Development reviews and payment intervals will decided as per agreement.
Hope to hear from you soon
Regards
Savitoj Cheema
