Aldevo;
This proposition would lose money. It would be a one note symphony.
Anyhow, you don't tell me capacity, sizes or anything so an estimate would be difficult.
In any event, assuming 35mm - LF, you need 2 supports, perhaps 3. One for 35mm, one for 120 and another for LF.
You will need chemical clearances and certification for all employees and a DEA license in the US. You will need about 50,000 square feet of plant space with a big cooler insulated against radiation to store product until shipping and you will need the plant to be divided into light and dark areas with foolproof light traps.
You need making, finishing, melting, coating, storing, slitting, chopping and packing areas. You need a huge air heater and chiller and humidifiers and dehumidifiers.
You will need a complete stock of rare and expensive chemicals such as heavy metals and sensitizing dyes which may cost about $100 - $200 US/ gram.
You need a staff of engineers and technicians. About 3 to run the machine and two professionals to back them up. You need about 10 to do the storing moving slitting chopping and packaging. You need the machines to go with all of this.
And, this does not include the R&D to start it up. It assumes you have all the knowhow in the people above, and own the proper formulas.
It is as complex as rocket science.
It will probably take over a year of financial support up front to get things going. Look at M&P restarting Lodima from a hand coated formula that worked! It has been nearly 2 years I think. IDK for sure and that was with a formula and a plant. They still, last I heard, have nothing salable.
That is why I express my pessimism over the schedule, nothing more.
My guess, starting from scratch is well over a million $ US and over a year. Starting with people, formulas and equipment all in place, at least a year. It would probably take in the hundreds of thousands in that case.
I estimate that getting Lodima up and running including all test coatings and the first run will cost between $50,000 and $100,000 and take about 6 more months from now. That will be close to 2 years or more with a plant and a formula. Of course, they may get lucky.
