A gallery shopping theme to do this?

Hello.
I run a photography business. I take a lot of images, I advertise them for sale as high quality prints of various standard sizes. I do my own matting and mounting in a selection of standard colours, and I build my own timber picture frames – a feature of my product.

I am looking for a good galelry software that allows me to do the following –
Allows people to view the website as a nice neat and tidy gallery / slideshow, for those that want to just view pretty pictures
Allows me to add a Buy it / Frame it / whatever customized button beside every image in the slideshow / gallery view (but can turn it off in thumbnail view when viewing multiple thumbs on a page)
When people click on the buy / preview button, it takes them to a page that allows various selections –
Matt or Gloss image (same price)
Just a print, or framed
If framed, select a matt colour, and allows me to load sample thumbs of matted images to demonstrate the image with the surrounding colour
Other useful features as they may be necessary.
I have been playing with ElegantThemes e-Store, and e-Shop intergration. But I think the problem is in interfacing something from the gallery, as all the gallery seems to do for me is view photos. I want to be able to intergrate the shopping side straight to the gallery without it being ugly, it needs to be a professional look.
Anyone interested in offering any advice? Happy to hear it and thank you for your time.
By the way, I know very little about widgets and sidebars and am really struggling and am prepared to pay for assistance, but I’m not rich, this is only a hobby that is trying to be turned into a business…
