Custom wordpress website will be done based on a boostrap wordpress framework. The differnce between html5 and wordpress is that the latter will have a adminstration panel where you can easily update content. I will be using a simple drag and drop builder in the backend. So it would be easier for you to update your website in future.
No specific design but website will be done based on your requirements.
Wordpress custom website design is suitable for any business just like html5 designs. The biggest advantage is you can manage your content and in future you can even add more additional features to wordpress content management system. So it is easily scalable compared to html5. So basically those who wants to update the website reguarly and have more control of the website must go for a wordpress based solution.
You can choose a package from above list based on number of pages and features your looking for. Then make sure to provide me the images and text information for the website as well.
