Hi Ali....aaah the old raster to vector conversion problem.

I am design & IT manager for a screen print company, so this is a problem I run into daily.

There are 2 ways you can tackle this:

1. Redraw the bitmap yourself (can be very time consuming depending on the complexity of the bitmap).
2. Use a rester to vector converter such as Corel Trace (which is part of Corel DRAW), or use the online service vectormagic: www.vectormagic.com

the vectors can then be split to separate layers / pages and bleed applied to each section as required.

Hope this helps...

Stu.
