What kind of city? Big? Small? Low/mid/high poly? Futuristic? Cartoonish? Modern? What would the rest of the positions apart from builder be doing? You’ll need to give some more information.
There is nothing telling us what the project is.
You say a city well there could be many options to make one.
Adding you on discord is a waste of time to find out more.
To hire people for your game, just giving us “a city with special stuff” is only helping the builder.
What kind of GFX do you want? Thumbnail, logo?
How much scripting? Small or large scale? How many scripters are you hiring?
Animation designers, what animations specifically?
UI Designers, what UI aspects? Tweening?
Please provide more information about each role, including some more insight on the builder. Also, try to please set out a budget for each developer hired, instead of bringing it all together to “5-10k,” people would like to know what percentage of that money goes to who. People doing more work should get more money.
Hopefully this can help improve, and thanks for reading!
