The ISPs don;t tend to accept route advers via BGP less than a /24. Some
do, but it has become some kind of a "standard"
If they allowed smaller route ads then the full BGP route table would be way
too large.

At a minimum you're going to need a single /24, not two. You would
announce this prefix on both connections. You're also going to need to
apply for an autonomous system number from ARIN. Details can be found
at www.arin.net.
I'm wondering what you're really trying to accomplish. If this extr

dificult for other isp managing this scenarioanyways everyone wants to reduce
routing tables and anouncing a whole class c is easy.

*sigh* There is no longer such a thing as a class C. There are /24
prefixes. Anyone who plans to do BGP routing _must_ understand the
difference, and why classful references are undesirable.
One thing that has not been mentioned is where the address space
comes from -- is it provider-assign
Thanks!
