Your existing business may be brandable but if it is not keyword-focused then you could come unstuck; unless you’re Google!
Think about where the new domain name will be used with your other promotional material; business cards, email addresses, leaflets, t-shirts, even mugs!
What about word of mouth or radio adverts? Is it easy pronounce and/or spell? No, then you probably need to go back to the domain drawing board.
Also think short but sweet. Admittedly some services or locations are long but in general a succinct domain is more like to be clicked by a user.
