Website Creation and Design

I am looking for a new website for my fintech consultancy business. I want a modern design which is optimised for desktop, tablet and mobile devices. Site needs to be dual language, English and Arabic and also be search engine optimised. There is no ecommerce required.

SIte will need to be published to the domain I have already purchased and I will require simple instructions on how to update images, content and add pages as needed.

As an example of they type of site I am looking for, penser.co.uk is a site that I like the design of. To be absolutely clear, I DO NOT want a simple copy of this site, its for reference only. However, the volume of content will be similar as we operate in the same field. I want a page where I can provide links to industry news and youtube videos where external content opens the content opens in a new tab.
I will also require the content for the pages that I provide to be translated from English to Arabic and pages formatted correctly for Arabic viewers

I need to be able to add/update content without the need for specialist software. I have MS Office

Thanks in advance
