Specialty keyboards like the TiPY are indeed very expensive, here in the EU it's a thousand (!) Euros:

However, if your relative is employed and needs to type for the job, then there's a good chance the employer will pay for it if it means they can work more efficiently during these months. Another option, which however is much less likely to succeed and will probably take much longer, is to try to get this through health insurance.
