App for iOS platform

We want to see events from a facebook account and choose one from the app. then only see event guests not all contacts. Wei want a new contact database in the app to store the facebook contacts and add more - not same as ios contacts Facebook event 1. I will create event on facebook not on app 2. App not need to make event or edit event - only checkin event guests. So this is just a database and facebook api then some forms to edit 3. Next match images to contacts - new table to store image name and contact id 4. Choose image from gallery, then search contact and make make relation ship 5. one image can have many contacts. one contact can have many image 6. Next is change image graphics to add text to image. 7. Select image from gallery. open thumbnail with textbox. add many contact id to text box. app matches contact id to contact name and writes the contact name onto the image and saves as new image in new folder 8. I will use bluetooth barcode reader to add contact id. i think it adds the number and a carriage return each scan 9. So text box will look like this : 12 65 89 87 many rows 10. When a guest arrives at the event we find them in event contacts or add them. then we give them wristband barcode id and add barcode id to contact records 11. Now we can scan contact after each photo and make record of who is in photo 12. On arrival the guest has photo and added to contact as contact image. now facebook post is made with photo and caption "xxxxxx has arrived" (john smith has arrived) can this be automatic facebook post after photo and checkin ? THERE WILL NOT BE ANY ADVANCE PAYMENT OR CREATION OF MILESTONE. WE WILL PAY YOU ONCE THE PROJECT IS COMPLETED. THIS IS A PILOT PROJECT AND WE WILL KEEP SUPPLYING PROJECT AFTER THE SUCCESSFUL COMPLETION ON THIS PROJECT.
