Develop a cross platform mobile app to score cross country for Eventing (an equestrian sport)

The app will have 4 screens, two very simple and two with a little more functionality (but still relatively simple).

We need IPhone, Android and Windows apps so most smart phones are covered.

The data must be sent to a MySQL server in an Amazon VPC. Its probably a good practice not to expose the MYSQL server itself to the internet so a web server will also be available as an intermediary.

If the phone loses data connection temporarily, the app must still keep functioning and store the results locally until the data can be transferred.

Although we won't be using the information initially, the GPS location of the phone should be included in the data sent (there are cross county map applications available so we will eventually show where the horse is on the track, using this GPS information).

There is a critical timing component where when the Start or Finish button is pressed, the time needs to be captured and sent (for timing the start and finish of the cross country track). The time must be accurate so the app needs to use a time from a time standard site (in case the phones time is wrong). The cross country time on track affects the score so the start and finish times must be synchronised.

At this stage, all the data flow is mainly one way (from the app). There may be a authorisation number sent back when the user first sets up for scoring. The amount of data is minimal, usually only a few fields from most forms. A cross country course will have 15 to 30 people scoring and horses would normally start between one minute and two minutes apart.

The project includes any coding on the web server to receive the data and save it in the MYSQL server.

Please indicate your interest and expertise level for this project.

Please indicate the architecture and development environment you recommend for cross platform development.

Please indicate in particular, how you would handle the timing issue where we need accurate times from different devices so the elapsed time can be calculated.

We are still finalising the graphics, so will give you an opportunity to fine tune your bid, but please put in an approximate cost. A couple of samples are included. One will be very simple and the other will have more logic in behind it (but not very complicated).
