We want someone to create a call script so we can move email data from a excel file placed on a server. To be sent into the email service called "get response". We want it to send x amount of emails sent through API every hour or so. Since we have x amount of get responses accounts we have many different API's, so we want to be able to plug a different api on the fly if needed so the email data can feed into a different get response account.

Hi, We are essentially done with the development of our app and social network. It is a design app with drawing and saving components. The final component is migrating all of the local storage caching aspects of the app to the Parse cloud. Presently, the user is prevented from doing stuff like saving images from other users' profiles, modifying them, etc. I will send an example of the app to prospective freelancers as the details are quite specific to the project. Overall, a successful candidate will be familiar with image caching, local and Cloud storage/retrieval of images for displaying, downloading, and sharing bitmaps.
