The same press can sit in a whole-seed crude-oil mill, a kernel cold-press line, a dewaxed clear-oil program, or a refined retail plant; those are different quotes.
Send seed form, dehulling target, cold or hot route, wax strategy, final container, byproduct outlet, utilities, tanks, and phase boundary before pricing.
Whole seed, partial dehull, clean kernel, residual hull target, and hull outlet.
Settling only, dewaxing, polishing filtration, refining handoff, or retail cold-test target.
Bulk tank, flexi-bag, tin, PET, glass, pouch, or private-label retail pack.

Pricing should follow the real handoff point, not a vague request for a sunflower oil machine.
Project fork
Simpler front end, darker oil, more wax and hull influence, usually bulk or refinery handoff.
Needs better dehulling, lower-temperature discipline, lighter oil positioning, and honest output expectations.
Adds chilling, hold time, filter capacity, cold-test agreement, and clean post-filter tanks.
Adds degumming, neutralization, bleaching, deodorization, filling, label, and carton boundary.

A short video of the existing workshop plus raw seed and oil samples usually answers more than a long text description.
