Add feature c# small hook with packet manipulation -- 2

hi how are you knowledgeable about game development and packet ? I built a small radar app in c# that compiles to a dll and use an injector called wp669 to hook to the game process and I need to add a few features on top of it :

select in game character within x radius with bound hotkey

parse combat event log in real time

only apply if you feel confident in such task to finish the job

price tag 300 dollar
