[Euro] Where to Install Mods and Cost?

Got the following Mods i plan to install(am selling some though)
does anyone know where i can get them installed and the cost of installation(i don't wanna get ripped off). I know some can be DIYed but i'm not really mechanically sound. Let me know if the DIY is idiot proof!It'll be great if there's one place where i can get everything installed. I'm located in sydney, eastern suburb.

Exedy Hyper single Clutch and Flywheel
