If you want your own DNS server to be authoritative for proyecto.com,
contact your registrar. You could still have the ISP run secondary servers
for your domain. Another option would be keeping the authority with your
ISP, but set up a hidden primary your ISP's secondaries would pull the
zone from.

If you want your own server to be authoritative only for
client.proyecto.com (I assume you accidentally left off the trailing "o")
and maybe other subdomains, you need to add delegation information, i.e.
NS and possibly A records, to the primary server for proyecto.com, e.g.:

$ORIGIN	proyecto.com.
client		NS	ns1.client
		NS	ns2.client
ns1.client	A	192.168.0.1
ns2.client	A	192.168.0.2
