I'm a Brit and off peak split by 3 = less targets + more time to contact.   It's slow...... we all agree.
May I suggest BRITS, EURO'S, AUSSIES, KEWI'S and the rest of the world contact advertising agencies and give said agencies HTC's address 
 
 Personally I know of a beat up old truck parked in a field by the side of the M6 
 thats bill board space is 3.95 per week <$5,50>.  A picture of a Spitfire shooting a ME109 and in big letters http://WWW.FLYACESHIGH.COM  is all thats needed.
M6 = couple of million vehicles a month.  Built 35 years ago and begging for a fourth lane.  Arterial motorway   Joins the M1 linking middle England to the North West.  Passes Birmingham .  Middle England Britains largest manufacturing base.  Motor industries, heavy industries, aircraft industries you name it, besides all the McD's, call centers,  Bank /Insurance HQ's.
The furrows in the slow lane are that deep that I can let go of my wagons steering wheel and I'll go straight.  Dunno about a fourth lane or another Toll road but them furrows need fixing.   .

Then again a full page add in the Sundays is a snip at $90,000.
