Pricing help - For the use of my fine art photo for limited copyright

Fellow proffesional photographers can you give me some advice?

I was contacted by an art consultation company in Sri Lanka that has a client interested in purchasing my fine art photograph to use in 41 of their rooms in a 5 star luxury hotel there. They want to get a quote from me for a limited copyright for that photo. They mentioned they have a contract that states that as well. I've tried doing some research and can't find my exact situation. I'm thinking around 3 thousand but I don't want to quote too little or too high. This is the largest sell I've had. I have to give my quote by Monday. Any advice or tips are greatly appreciated. Thank you

Here's the link to the photograph:

Sri Lanka is in South East Asia and yes it is legitimate. I think the print would be a larger size they will use so actually if you were to calculate that it would be closer to 4 thousand. Since they will be printing it themselves and it's giving away like a limited copyright and I feel the price should be a different approach. Thanks for the reply though.
