I'm looking for someone who can build a phone application for me (IOS and ANDROID).
The application is pretty simple.
I would like to create a flash sale application. When the customer enter in the application, he will have 1 Flash sale available and only one, with a timer. The flash sale will have picture, price.
There will be a page to explain the website.
If he wants to buy the product, he can push a button and pay with credit card or paypal.
I need a back office to schedule my sales for the week and a back office for customers account.
I want to know the budget i need for this kind of application.
