I need some modifications to this: http://smartphpcalendar.com/ I attempted to get in touch with the author for several months without any luck, so if you think you can do it, let me know. There is a brief overview of the API here: http://smartphpcalendar.com/documentation/calendar-client-api/ Tutorial on how to customize dialogs: http://smartphpcalendar.com/documentation/tutorials/customizing-event-dialogs Here's what I need: Checkbox field called 'invoiced' Checkbox field called 'sub contractor' Dropdown field called 'staus'. Should only be seen when editing an existing event. The color of the event should change depending on the status. Red for 'Pending', Yellow for 'In-Progress' and green for 'Done/Finished'. I have a custom file by the author which will allow you to do that. All of the names should be translatable by the i18n system, that the application use. Changes from the original files to the finished files should be clearly marked in a separate file/documentation. The text on the events displayed in the calendar should be changed, so that it shows a little 'tick' in the corner if the event is marked as invoiced. I will provide FTP login, Sql database, PHP my admin. You will receive an untouched source code, and the extra file as mentioned in the requirements. Timeframe : Less than two weeks. Payment method: Via paypal only. Payment will be shipped: When I can view a functional demo with all of my features requested above. There will be no payments upfront or during the process. This is only to ensure that you stick with your offer. This demo may be an uploaded video, sharing a screen, extensive use of screenshots, or uploaded somewhere. Terms: Should you exceed the the two weeks without letting me know of it beforehand, your off the job, and no payments will be made. If interested, let me know your price, and how long it will take you, either by PM or by replying.
