Yes thats true, most my little patio jobs like that now are priced up via images, I gauge an idea of whether it's worth going over pricing for over the phone, if it's too far or sounds small, then I won't even go and price it, they have to send me a picture via text / email / etc. I personally live in quite a populated area and would never even think of travelling more than 15 mins to price the job unless I was passing or it sounded like a nice pricey job
i honestly don't have time to go doing unpaid driving trips pricing jobs up, I also tell this to my customers who seem to appreciate this, they must think 'he's busy, he must be good! haha, and then they send me a picture, I have it on my website as eco friendly pricing
