So your looking for local shops from a certain local that sell lamps?
Like you have keywords for

or something?
I mean you just put in your keywords into the keywords box and then you search whichever engine you want to get results from, like say google. Then the results will be what google things is most relevant and you would probably have a decent list, at least in the initial results. The deeper you dig into the results the less relevant they will be.
