Hello there and Happy New Year!
We are a software development company focused on creating custom-made software solutions.
I went through your example sites and I am happy to offer you a custom-made dynamic website, which includes user-friendly Content Management System so you will be able to edit and update the text, images, multimedia etc of your site.
And something more - we provide life time warranty for all our products. So, if you ever find some problem with your site you can contact us and we will fix it for free, in a short period.
And at the end one question - do you really want a site of one long page and with no navigation? All the examples you give are like this.
Regards
ClearWare Sales Team
