Lets discuss your project description:
First of all i would like to know about framework, like
Is this WP framework ?
Is this any design which is you calling this framework ? as BootStrap,Less, Sass etc etc, its just an example no need to confuse :)
Or its back end framework ?
Exact design :
Too keep this design its very simple and easy, so its not a big deal not at all, even we can make this better if you guys suggest us.
No Commercial theme installing:
As you people provide that framework and do not want to use custom theming and plugins except Contact form7 and Advanced custom fields, fine.
Solution: We would like to build custom theme by using WordPress custom API which is best option ever(like theme forest did), where we can modify code and design according to our scope without any limitations.
Content: Content will be insert by you, good to know, but i can help if need any anywhere
Templates: Working on templates specially in WordPress its a good approach.
About me: I am senioer WordPress/PHP/MYSQL/API'S developer and have very convient sources of developers and designers as well.
Looking forward.
Thanks :)
