Hello
I have watched your video with instructions and also took a look at files you provided. So, from my point of view, its typical PSD to Wordpress job, BUT this one will require a bit more CSS coding so i can achieve three different looks. Of course, i plan to use premium theme for this, Enfold, in this case, cause its very well suppored, with regular updates. It also offers best backend control panel and one of the best builders i even worked with, so its perfect for making custom layouts like yours. Using child theme, and just a few needed plugins is good option, and i like to make some small php code changes if needed, more then installing another plugin that will just slow down whole thing.
I can buy this theme for you, or you can buy it. If you buy it, we can talk for lower price then i offered in my bid. If i buy licence for you, that will be the only upfront price i will be asking for. Rest will be paid upon job finished per PSDs you provided.
I will have few questions for you regarding resolutions, cause not all people consider tablet or phone view to be same resolution, so i will need to know which resolution will be trigger for each view. Enfold and custom CSS will take care of the rest :)
I usually work long term jobs covered with NDAs, so i am not allowed to post my work in my portfolio, but i can point you to some of them, mostly PSD to final work.
So, feel free to contact me if you have any questions for me.
