Hello WSF,
This is a great project creating a showpiece product launch for Doug Daniel. We work with Wordpress on a day to day basis - with everything from installing wordpress on a server to custom themes.
As a first comment its excellent to hear that you have most of the content ready, a clear structure for the development, and an open mind.
We are happy to work in line with the workflow you have detailed.
Secondly I would like to suggest to keep your options open in terms of the theme. From the video you have uploaded and the currently visible structure on your site I am not filled with confidence in it. If you notice on the video the wordpress is from many releases ago and from instinct I believe the theme has not been kept up to date. Its best we ensure the excellence of your product really shines through every aspect of the site.
I look forward to discussing this further with you,
Kind regards,
David Anderton
NG Development
