Unity 3D (ONLY) Dev Team Needed ($400/monthly)

Business app developer, looking for 24/7 team to maintain and update UNITY 3D business app. Must use UNITY3D only, and have skills in C#, passing data via PHP to an SQL database. Also need this team to be able to add plugins and New UI and New Programmed functions, to existing app at a moment's notice and be able to quickly implement new Functions. Budget is only $400 USD per month, with many days off (3 to 4 days off work), in between intense work hours (usually 3 days of 10 to 12 hours) when new function suddenly needs to be added, or a fix must be made. Submission Skills: Team must also be able to upload screenshots and final app to iTunesConnect and GooglePlay for tresting and final submission. Must be proficient in English. Again, don't waste my time if you don't use UNITY 3D. UNITY 3D only for this project.
