Most people on this forum are in USA, myself included. Thus, what is available to us might not be easy for you to obtain for forks.
If you considered 26 inch wheels instead of 29, Thorn (in UK) makes a fork that is suspension corrected that you could put on a bike that currently has an 80 to 100 mm travel suspension fork. The link below is for rim brakes, for reasons that I do not understand they put the brakes behind instead of in front of the fork. That is the only source of a rigid fork that I am aware of in Europe.
