Hi Christy
Why not use blind micro-vias they allow the free placement of components
on either side of a board and can also be placed in the solder pads
without adversely effecting soldering due too their small size.
This would give you the complete freedom of design.
You might look at http://www.dyconex.com which has large sections
devoted to micro-via design.
