I have been approached by "high end" store here in our hometown. Let me explain high end for here. The most "normal" people here make is about $30,000 with and average of maybe $25,000 a year. There are 2 millionaires but thats it

This is an entire county not just a town.
With that said what size photos would you have up for display. This isn't for my portrait work but my landscapes, flowers etc... Don't expect a lot out of this but I figured what the heck. She is only charging me 10% of the sale IF sale anything.
What kind of frames would you use? Size of prints? Would you mat them normally or would you do a mat in photoshop?
I need feed back.
Thanks
