Basically, the ECU software I would recommend would be Uprev. That is $700 for the tuner version. A tune will vary depending on shop, however I'm happy to recommend DVS Jez. You can enquire about his rates.
That leaves the fitting and fabrication depending on how you want to configure the kit. A member on here has Sump extension available to suit, and has offered it for $80. Will just need a fitting in the side for the oil return. The fabrication work is very small, basically adjustment to the angle of pipes, however I can't quote the price, as I'm not a fabricator!
Fitting the Kit - I will have to enquire around before I can make an figure. There may be fitting options in Sydney and Melb, however I can't confirm this until I have spoken to some people.
What I forgot to mention - the kit comes with instructions (both hard and soft copies for the buyer) but they are in Japanese. The pics are helpful, and you can run the PDF through translator if your installing yourself.
