What you are showing is along the lines of the old UK kits from Jim Fox, (those even had beech sheeted wings) "ARF" should not be used in the same sentence. Its a builders kit. This is fine and needed in the marketplace. But to provide a price would need a clear scope of work to be completed. Adding one scale feature can be 10s of hours, and as noted with these larger scale models, not many folks would be satisfied with a smooth surfaced wing on an aircraft that has so many unique features. they are looking for those details adding hours.. The pictures are not showing enough to really judge.. Do the cores have spar cuts and servo openings? is the sheeting provided or is all the wood separate. Find a reputable builder and ship him what you plan on providing as a base and see what questions he has to provide a proposal.
Could you partner with LDS to provide a laser cut wood package? Those things could help you define your pricing
