JPcinemamaster is talking about potential clients as opposed to actual clients. This makes the situation a wee bit different.
What I do...
As I don't do any advertising outside of my website all of my clients come to me either through my online enquiry form or via referals. My enquiry submission asks them if they want me to call them. If they say no then I don't as there seems to be an extraordinary number of time wasters looking for websites!
I respond appropriately by email requesting more information or if they have provided enough info I tell them roughly what they can expect to pay. I also ask them if this is within their budget. If they do not respond I contact them again in about two weeks time to jog them. If they ignore this I drop them into the can.
