There are several ways you can affect how traffic enters your autonomous
system. The most popular is prepending your autonomous system number 1 or
more times on your outbound announcements. Though, some find that
prepending is not granular enough.
You can go a step further, and prepend outbound only on specific prefixes.
Some ISP's also will allow you to set certain communites on your outbound
announcements and alter how they announce your networks to their peers.
Inquire with you ISP's as to whether they implement any such features.
Some of this is dependent upon the size of your announcements, though. If
you're announcing a /24, and it can be aggregated into a /8 at your ISP's
borders, it's not likely that your ISP will announce a specific just for
the benefit of your traffic flows.
Internet Routing Architectures is an excellent book by Sam Halabi that you
may wish to reference. Also of value is BGP4: Inter-Domain Routing in the
Internet by John Stewart III.
Good luck!

Suppose we have the situation as posed below but I need to manipulate how
