I would imagine (although I am making a lot of assumptions here) that Landing pages will be crucial part of your particular strategy, once you have the clicks coming in.
James has provided some great suggestions already.
If you have the customer segmentation brake down already, you can create landing pages and corresponding ad groups based on those customer segments. For example, your customers for residential chandelier cleaning could be broken into regional areas (cities, zip codes, etc.), by gender, by income range, by different types of residences (owner occupied, or single family home rented out, etc.), etc.
