Hello! I can get this finished within the next 24 hours.
1) If you can tell me how you want it rounded, I can just implement the functions to automatically convert it and update the text, eliminating data entry work, so that should only be about 30 minutes or so to get it plugged into the relevant UI panels.
2) Do you currently have any other plugins or SDKs that use Google Play Games Services? As long as nothing else exists, this would only take an hour or two to get signin and achievements hooked into gameplay logic. Also, would you be creating them on the console and giving me the leaderboard and achievement code to paste into Unity, or will I need to do that and supply icons as well?
3) Do you already have the UI setup to facilitate this? I assume you have a main menu with locked portions that unlock once purchased. Should be another hour for this.
4) Who are you using for an ad network? Depending on network and integrations required, 30mins-hour.
5) Which social networks? This would take the most time, depending on how many and which ones probably 2-4 hours for this part.
Overall I anticipate this to be finished this evening, or at most early tomorrow morning (I"m EST in WV, USA) as I have nothing to do at this point, having already finished two projects today.
Please let me know if you have any questions,
Adam
