Y'ello, i've read your thread carefully, basically you want a working multilingual (spanish and english) template, with contact form 7, (which is free) and fully responsable, all of the content obviusly would be editable, with the slider revolution, and the clickable phones, all of that can be achieve, now the Visual composer, it's paid, are you providing it ? i have a copy, that can be used, but still, thats a big question, regarding the SEO, yoast seo plugin can be added. The sections themselves has nothing that is really big on doing. I can give you a full price for the two sites, lets say around 950 (not each, but you get two by that price) .
I really hope we get to work together, btw, currently im at Panamá.
