Storyline 360 drag and drop with timer

Hi I am looking for quotes for the following drag and drop game in storyline 360. I am NOT looking for the look and feel. I am ONLY looking for the functionality, so it can include dummy data, but everything should be labelled clearly. Your quote must include me receiving all source files as part of the deliverables. The finished solution must allow me to change all variables easily - timer duration/text fields/etc The drag and drop game should include the following: Overview: - allow users to match 12 drag items to 12 drop locations (all text). Required functionality: - Needs to incorporate a countdown timer - Needs to incorporate a separate button to reveal pop up text box at any time for reference and which can be closed again at any time (without affecting countdown timer) - Needs to be fully accessible (WCAG 2.1 AA) across tablet, laptop or desktop (not mobile and NOT including the timer) - When timer ends, then whatever is correctly matched stays in place and all other incorrect matches revert to start position. - Done button if user feels they've finished before timer. Functionality is then the same as if timer ended. - Reveal letters button - 'reveal letters button' reveals a single letter on each correct match in place - Needs to mark answers and award point for each correct match Ideal functionality: Check button – can click at any time, any wrong matches currently in place go back to start position, correct ones stay in place (again should not affect countdown timer) Extra points for matching all of them in the allocated time Please let me know the cost for the finished, functioning .story file and when you can complete it by, and how many revisions are included in your quote please. Many thanks!
