Now really sure that it'll help you, but in Kazakhstan digital signatures can be legally significant (have equal significance as hand-written signatures) in case if several requirements are met.

One of the requirements is that certificate has to be issued by accredited CA. And there is one such CA - National CA (https://pki.gov.kz/), it issues such certificates for free.

Also there is a service that allows anyone to sign any file using a certificate issued by National CA - https://sigex.kz, thus making it legally significant. It's free for use (except for heavy RPS enterprise users and the ones, how need support).

So in Kazakhstan you can do e-docs signed by e-signs totally for free.

P.S.: Pardon, but the links are in Russian.
