You are a junior developer that needs assistance with a Unity project? Your game is crashing, your ads are not showing, your app's frame rate is dropping, your textures/sprites are not looking right, you don't understand mechanim animation system, or you just don't have enough knowledge on 3d graphic/game development related stuff such as navigation meshes, GI lightning system, materials/draw calls optimisation, or anything else. Then I can aid you in the right direction if I don't fix your issue.
If you want to make sure I'm capable of doing so, then just contact me with any concern you may have regarding my knowledge/experience before getting my full assistance.
The 5$ gig is just for a 20 minute TeamViewer/Skype session.
