To whom it may concern,

We are Victor and Ruben. Two skilled engineers with a new idea for an app. We are looking for someone to build our concept ideas into a fully working product. For the first release we would like a really simple and effective app. Keeping costs as constraint as possible.

Essentially, it is an app that allows customers and business to be connected in order to avoid queuing times at peak hours. The user can set up their preferred area and the app would need to search the included restaurants around it. Users should also be able to search restaurants around their position. On one hand, it will allow customers to easily have their meal pre ordered and paid so, once they get to the takeaway restaurant, they only have to pick up their meal. On the other hand, the business can receive, confirm and prepare customer orders in advanced. Time slots for collection will be automatically managed through the app to prevent queues to be formed at the pickup.

The Main focus of the app is to deliver correctly this customer-business relation. However, it is important to keep in mind that we want to build it over a database in order to process and analyze the data gathered from all users of the app (location data, money spent, places visited, popular dishes, popular restaurants, popular areas, etc). Which technology would you use here? Have you done this kind of project before?

Ideally, the app should be built for Android and iOS on the user side and for Android on the business side. The idea is that everything revolves around a database and the apps are tools to communicate with such database.

We have made a mockup design of the app that can be found in here:

App for Business: https://marvelapp.com/7341ch6
App for Users: https://marvelapp.com/33ci97c

We have tried to get everything pretty clearly. However, further explanation might be needed. This is why we would like to work through a Hangouts group where calls can be set up and we could chat about everything related to the project.

Features that the app must include:
Database Managing:
User profiles
Restaurant database (business profiles)
Dish management
Sign-up and Login services
Google
Facebook
Email, Pass & Details
Payment Method system:
Card details from the user that are used to pay orders (whose price is specified in the app).
Bank details from the business owner in order to receive the money.
Invoicing system to comply with the rules and regulations of app transactions (Email system that sends the order receipt to the user and to the business?)
Location services:
Track where users are in order to give restaurant suggestions around them in the app
Push Notification features:
Display important information along the customer’s order journey

Aside from these requests, we would like to ask some more questions:

Would we have access to the code you are writing at all times and get it all (with full rights to use it) at the end of the project?
What kind of support will we receive along the project and once the project has finished? Is it possible to work with you for successive updates? 
What development path would it be optimal regarding the implementation costs? We thought about first developing the Android apps which are cheaper and then you can mimic the final product on iOS to prevent extra costs adjusting both apps at the same time.
Would it impact the budget the fact that we are able to imply ourselves with the design process, thus reducing the amount of hours spent on designing?
What are the specifications of the payment methods you use? How secure are they? What are the prices of using them?

We are very excited to push this project forward and would like to see if you are the right partner for it. Could you please get back to us as soon as possible with the answers to the questions, estimated budget (price per hour) and implementation time? When would be your earliest available time to set up a meeting after your response?

We are really looking forward to your response.

Best Regards,

The Gambit App Team
