What would get you to drive 50 miles and take several hours out of your busy schedule?
Why do I need to?
Now, let me say I'm in Canada - I'm just a small photographer, and my 2c is well....recently harmonized and has more tax than substance. So, here's a story.
Years ago I owned a retail store (it was pet food) - anyway, I dealt with many suppliers to purchase stock. Since it was repeat order type business, they all wanted me to order from them. To get me to pick them over their competitor (who offered the exact same stock), for some reason they all wanted me to drive out to their warehouse to look at skids.
Something about my looking at their SKU's on skids on cement floors was supposed to ignite my passion. Here I am flogging kibble every day in my store, working hard to develop my own customer base, and these guys think its a day at the spa to tromp around and look at SKU's.
There was one guy who opened his warehouse about 1 month before me. He wanted me to go - several times he invited me. When I didn't go - he provided picutres. He had uber shiny computers, fancy paint, and skids...with pet food on them (surprise).
Yup, He was fancy, he was pretty..he went broke in 6 months.
So, here's my view on your offer. I make more per hour each day than it costs me to produce a canvas print (talking the manufacturing side of things - not the actual time to photograph the image). So, for me, its not an incentive. And by definition, I would think pro photographers already know how to produce one - some might feel better than you can?
For me to drive 50 miles and spend several hours away - I would have to believe I'm going to leave with something more than a print. What's more valuable? KNOWLEDGE. SKILL. INNOVATION.
If you have found the cure for cancer - yeah, I think I might find time. Or, maybe you don't have a cure, but you have some brilliant physicist who knows everything about the molecular form of cancer, and can provide a really good theory on how I might cure it.
Otherwise, I will troll the internet, hang out on forums like this where the good people offer free advice just for the asking, and take my chances.
Edited to add: Good luck
