Create / Re-write our website content - (Engineering firm specializing in Building Fire and Safety)

We are an engineering company based in Egypt specializing in fire protection, building safety and security systems. we represent some brands on trading basis at the same time we do installation, maintenance and some design work. We are revamping our website and have finalized the design part. what is missing in the content. I have some content that is ready that needs proof reading, other segments of the website dont have much content and I would like to write some paragraphs for the site at the same time being SEO friendly to match with our decent google ranking. Each section will be explained clearly if needed to understand anything technical. You can visit our current website at : www.unisafe.com.eg The following is a draft of our new design: https://xd.adobe.com/view/29417d1e-2aff-4ff5-967c-2472f6eb6d13-7c12/ Attached is also the content draft which was done back in 2025. This is not very good and need an overhaul from writing style to being internet friendly but it gives an idea where to start. There are a couple of sections which are a bit personal (history of the company etc.. that can be given as points or bullets and put into proper writing). We would like to overhaul and re-do the whole website content. We do have authorization to take any content or marketing material from our suppliers. I will list them along with their websites in detail so that will help alot when it comes to content. Upon contract, I will update the list of suppliers and provide specific product sections on their website where some information can be taken. Thank you for your time and if anything is unclear please let me know. Thanks!
