Programador mobile

Hello, I consulted because I need to develop an app for a gym. With an administration panel. 
It should be for iOS, Android and Win.
With the ability to translate into Spanish. 
Ability to change the logo of the app and contact details from the admin panel as well as any content of app.
Approximate times and project costs.

Sections:
00- Login: classic, Gmail, Facebook, Instagram y Twitter.
01- About Us & Contact Us Pages: their gym information, contact details and address map (should put a contact form?)
02- Gym Programs (WODs of day): display their gym workout programs to fitness, list of exercises with short description text, video exercise technique and images.

03- Notifications: push notifications of due dates fee gym, reminders and institutional notices
      - *Automatic notification to each partner 7 days before the expiration of the gym membership.
      - *Automatic notification to each member the same day the expiration of the gym membership.
      -  Notificaciones staff
*The initial payment date must be entered manually (app admin panel) for each user for the first time to later enable automatic notifications.

06- Trainers: profiles, specialties and other info.
07- Special offers and promotions: functionality auto-share on social networks (facebook, instagram, twitter)

-  Awesome & intuitive ui-ux
-  retina suport
-  feature to create different plans with their respective amounts and assign each customer to install the app.
-  Feature to register via admin panel app payments gym customers (status: payment-default).

-  Feature Assistance to the gym:
Use the geolocation service to pass presentiment of client attend classes in the gym. When the member enters the gym the app will access records: date, day and time. The idea is that the app is activated at the least possible meters.
Avoiding that if the customer without intending to go to the gym come to pass around the corner, the system does not record the present to the class that day.

- Feature Defaulter customer notification
Alert Feature Admin Panel alert from the app as a reminder via email the administrator user when the client pass and the expiration of your membership fee this within 3 days, when the day of expiration and when due.

Remain wing wait for any consultation.
Best regards!
