Well, Technicolor is a well known vendor and should give you all the support you need.
But the basic steps are those.
1. You need to provide a calibrated viewing solution to a standard you both can settle on. Normally P3 on a projector or monitor.
2. Your client need to settle on a stock used, either Vision or Prime.
3. They need to provide you with a LUT that simulates that exact process.
On the other hand, Cinevator uses its own LUT box , does not go through the negative pipeline and is much easier to control.
Its important to show them your source material and talk it through, then settle on a 2 minute print test , early in the process and all will be fine.
