The citizens from the UK, Canada and China (and others...) have been indeed removed from the e-Visa list, and the only alternative is to get a paper visa.
Contrary to some other countries, VFS (the commercial partner of the Government of India for visa services) doesn't allow to pay for priority so, apart from finding an appointmemt, in the UK you're out of options.
And you can't apply abroad either, as they require the sponsoring business to be based, and the applicant to reside in the country of application.
