bp3494 that sounds great! - I hope all plans work out well, I would recommend keeping pricing identical to that of the outdoor theater to keep competitive.
However on the other hand, the outdoor theater sounds great why not just give them an offer for the business? The old church may need a new air conditioner installed to make it comfortable for patrons, It would need a Projection box, and either two 35mm film projectors or one 35mm film projector and a platter or finally but most expensive a digital projector ranging from $90,000-$250,000. The building would also need a commercial sound system, comfortable seating, a screen, masking (black curtains around the screen), carpeting for acoustics, a newly built concession stand and ticket booth, and lastly a new sign!
Always remember that the film company gets from 20%-90% of every ticket sold, so if you sell a ticket for $5 to a newly released film you may only see $1 per ticket of the gross profit.
Anyway, I urge you consider offering to purchase the current theatre to save all the hassle of the fit out, equipment, and marketing etc. And don't worry you have 40 YEARS experience in retail just keep reading the forums on this website!
All the best, and if you have ANY question do not hesitate to ask,
thanks Sam.
