Write an iPhone & Android application

I need a mobile app created (for BOTH iPhone/iPad & Android/tablets; iTunes and Google Play). This app will be a FREE download for customers. 1. Once customers download and install app they will need to enter PIN to access their files on an already existing company database. Each time they open the app they must be required to enter PIN for security reasons. 2. All customers are in current company database and each customer has a unique file. The app needs to allow customers to see ONLY their own file (PDF documents, appointment dates, and notices from company). So the app (customer) needs to be able to read their own information file through the app. The app needs to be tied into the database. 3. Customers should not be able to change ANYTHING in the file. Read-only capabilities. 4. Push notification (vibrate) for appointments set by company is needed. When the company set's an appointment, the customer should be notified (vibrate). NOTE: Only the company can make appointments. The customer cannot set, make, or change appointments. 5. Access device calendar - we want this only if when the date changes the app/calandar will delete the old date. In other words when the company wants to change an appointment, the old appointment is deleted and the new one create - with push notification to the customer. If the old date is not deleted when a new one is created, then we don't want this service included (so quote price accordingly). NOTE: Only the company can make appointments. The customer cannot set, make, or change appointments. 6. Branding, logo, and design work should be included in quote. If you do not offer this service then quote accordingly and send me a note so that I may get my graphic designer to do it. 7. Delivery, upload, and testing to our iOS Developer and Android Developer accounts should be included in quote also. If there is any part of this that you do not typically include, then give quote along with a note that explains what is not included. Also, please include your additional services and guarantees that are included. Please give an estimated timeline for this project.
