Which Theme / Plugin I need?

Hi

I have customer with specific wishes and I’m digging around few days but I don’t find great idea so far.

Here is what I need and I’ll be more than happy if I’ll get some ideas.

Page must be nice, fashion, sexy, likable … In front page must be big, clear pictures with infinity scrolling (1 or 2 in row) – like FB, instagram, … Theme must be responsive – we have big focus on mobile. When someone click to image must go to the post. In this post he’ll see this image and contact information – profile data, mail, location, phone…

Then I need front end for creating new posts. This will be some kind of 2nd hand store with multi vendors – but without chart, just contact information. It would be excellent if I could insert this post with mobile phone – someone take a picture with phone and upload this picture to post, select categories and click “publish”.

Probably I must start with BuddyPress. But what next? Woocommerce have to much options (importing must be easy as possible).

Can anyone please suggest me, what sources I can use for this.

Thanks, Dixx
