Hi, if you can provide further details of the manual operations of these shutters (Lever, pulley, ect) and you are planning to buy the necessary hardware yourself if I specify what you need(Microcontroller, motor, ect; Probably around £50 tops) then I can create a list of parts, all the necessary software, and extended documentation for set up and maintenance ASAP. I expect I could produce an initial draft within 2 days with the remaining allocated time for you to construct and verify the functionality of the system.
If you would prefer me to buy, construct, and build the system myself then I'm happy to do that(Assuming you're in the UK I could ship it to you easily) however the cost of parts would of course have to be added onto the budget stated above.
