Hi,
Assume you know the price of the laser devices ?
Trouble is you do not really define your current and future needs very well; basic things like board size, volume / quantity per day, etc etc
At seemingly $75,000 a pop over 7 years that $10,000 year for bare prototype boards without tinning, plating though, coatings or silks etc etc.
That does not seem economic to me, surely a local pcb manufacturer would give you a complete pcb at a good price and turnaround to a regular trade customer.
