Is my approach to WP customisation correct?

Hi Sitepoint Wordpress experts,

Please have a look at my approach to re-design and [re-development of my website](http://www.simplogy.com/2011/09/our-planned-redesign-re-build-wordpress- thesis-customisation-specialists/).

Do you agree with me as the approach I have taken. To build wireframes, get them re-designed by a specialist designer and then looking for customisation services for WP.

I am told that design and development should be both done by a single person so that WP+Thesis is kept in mind at design stage. However, I am not sure.

If you may recommend a developer who may help, please feel free to refer. Or, could you give me an idea of how much should be the budget for this customisation?

Thank you very much
