Lionheart, if you read my post, you will see i mention that domestic customers appriciate this approach/image. However you are quite correct in saying the higher end of the market - commercial work for example will require proffesional looking literature.
I do design work for some massive brands i.e Coca Cola, Budweiser, Stella Artios, Nestle, Gillette. All of which require the utmost proffesional cutting edge design. But for my flyers i will definatly have two lots, one for the commercial market and one for the domestic market.
Don't get me wrong, the domestic customers who don't throw your leaflet away thinking its just another crappy gas/loans/insurance flyer, will really appriciate the proffesional information/approach. Its just the initail stage of getting the potential customer to read it thats tricky.... Think of it this way.. if a glossy leaflet & a handwritten note came in the post, you would definatly read the hand written note but would most likely throw the leaflet away... this is because its more personal to the customer
Business cards are good as you don't really get these come through the post as junk mail, so these will have a better chance of being read.
Just an insight into the way us marketing guys work in getting people to adknowledge what your talking about.
