Wrong device forum, but I'll help ya.
Install your SBF that's missing the market. Don't modify it.
Once you're up and running, go into your recovery and install the gapps.zip that matches your Android version (gb, ics, etc.) as an update. It will add the Google apps to your ROM's read-only filesystem. (This is done on the device, not from the PC.)
If that doesn't work, you could always just look for a com.android.vending APK....
