2 logos becoming 1

Hi, i need 2 logos combining into 1. It doesnt need redesigning from scratch, just simply a new logo combining both old logos.

ie These were 2 different companies, now one company is the main one. So we need to show the lesser company is owned by the bigger one, ie Welcome to "company 1" by "company 2" - but in a decent logo format. If that makes sense.

I wont lie or waste anyones time, but we need this as cheap as possible.
