Creation of an Image gallery template

Hi, I am a photographer and I need to show my clients galleries of their pictures. Today I use a service called [login to view URL] example: [login to view URL] I like: * the interface * the presentation of the first picture (personalized cover) * the mobile friendly approach I do not like: * once you scroll down, the pictures show as in "pinterest" with a "mosaique' style display for the gallery. What I would like to do: * I'd like the same "template", but instead of having a mosaique style gallery, I would like the pictures to display one below the other (like in a blog). * All the pictures should show at full size like the "cover picture" (the first picture), but with a mobile friendly approach (pictures size adapting to screen size). * people can either scroll down or use the arrow key to go to next picture (like on pixieset for the first picture) * i'd like the same options like on pixieset (download, share on facebook, like) * I'd like to keep the same kind of interface as pixieset, simple, smart, userfriendly and clean. . Basically I would like the same as pixieset, but to go from: * "today - mosaique gallery style" (see picture attached) to * "future - blog gallery style" (see picture attached) Are you up for that job ? Thanks Fred ps: if this works out, i will most probably ask you to develop other styles of galleries as well, but let's test first.
