large format printing of image on photo paper

[popprincess]

Hope this is the right forum. I am new.

I am hoping to find a studio/company/lab that will take a slide or image from me and develop/print it on LARGE photo paper. I have only found places that will print up to 48" wide and any length, but I want to go bigger!
I do not want to print digitally......

Thanks for any advice.
