Just did it last weekend and as soon as the photog sends the pics over I will share. She offered to pay as this couple were getting married at a little brick church with no photo ops really. I requested a couple emailed copies of the pics to use on my blog and website and we can recipricate links. She was over the moon with that idea!
Well turned out, as I was gone when they arrived, that it was a US Marine in full dress and his bride. The breakfast table the next day was very excited about seeing this photo shoot in our gardens.
Before accepting, I made sure it was not a wedding PARTY as we had this a couple times and they took over the property and were VERY loud nothng bad, just laughing and enjoying themselves (Oh and requesting to use our bathroom! We don't have a public bathroom, I tell them this upfront now).
I have also allowed prom kids here to photo shoot outside, that is even worse, it ends up about 8 to 10 couples, their parents, aunts uncles etc and fills up the parking lot (So I tell them where they can park in advance). I have no idea why they all came along, but they did! So from those seniors the word is spread and it has become an annual occurrence. I will ask for some of those pics as well. Just because they are probably better quality images than what I take.
Hope it works out for you! I figure in my case it is word of mouth advertising, each person who gets a copy of the photo or photos will be told where it was taken..
