I apologise for not answering in English.

1. For /24 assignments (and shorter, like /23), get the client to 
   set up a nameserver with the correct reverse zone in it
2. Find a secondary nameserver. As their ISP, you should consider running
   secondary for the zone, once you verified their work.
3. Once all this is operational, apply for reverse delegation at AfriNIC
   using their standard procedures.

For /25 and longer prefixes, have a look at RFC2317.
Create a zone for the /24 upwards, get a good nameserver set,
then delegate out of this zone (which you now control) using
the techniques described in 2317.

Hope this helps,
