We have developed a basic proof-of-concept app which projects a few functions from a larger enterprise application onto an iPhone app. The first version of this app is in production use. The app communicates via secure web-services to production servers to populate the data for the operation of the app functions.
We now wish to start a program of significantly enhancing the functions provided by this app over a series of incremental releases and we are seeking a suitable contractor partner to work with us to this end.
It is a medium-term objective to also develop iPad versions of this app in future and to deploy across other mobile platforms such as Android.
The intention is use fixed-price arrangements for the initial releases until such time as some confidence has been built up with a contractor partner at which time we will then also consider time-charge arrangements.
This first upgrade ([url removed, login to view]) is quite minor in scope but cleans up some parts of the initial release and introduces minor additional functionality.
We will only evaluate submissions from contractors who have a previous positive track record and who can demonstrate previous iPhone development capabilities to the level we require.
We will evaluate all appropriate submissions where it is clear that the developer has the necessary experience to undertake and complete the work professionally at a competitive price. We will determine this by reference to portfolio information provided which clearly show-cases the iPhone mobile app development capabilities of the applicant.
Whilst our primary selection criteria will be based on native iPhone development capabilities, we may also be influenced by proven skills in other areas such as iPad development, HTML5 development and quality graphics generation/modification capabilities.
