/24 is my own subnet from RIPE not from any of my provider.

presumably what you mean here is you have two leased lines, one provider has

assigned you a /24 and you dont say what you have from the other and you
want to 
have inbound and outbound balancing/redundancy

you need to speak to both providers to see what they are willing to do, the
giving you the /24 may not permit the other to route it, either may not
agree to 
routing the /24 independently without changing the agreement and cost - they
not wish to do it at all

you pretty much have to get an AS number, these are usually trivial to
for a network in your position (having two providers). then you'll need to
it routed.. you can either do this on your own equipment running bgp or
soemtimes the providers will agree to announce it from your ASN on your
the latter provides less redundancy but can help you avoid buying and 
maintaining a bgp capable router
