if you live in America, there is a federal/state agency called the Division of Vocational Rehabilitation that can pay for work-related equipment, even if you are already employed. be aware that they are overwhelmed and under funded, and the application/waiting period rivals that of the V.A. (looooooong). still, they might be able to refer you to an Independent Living Center in your area that is much faster, tho poor, which would know of possible office equipment donors..
