Bilingual Arabic/English company website with an Arabic admin panel

Hi I need a website for a company in Arabic and English (RTL and LTR) with a custom design, not a ready-made template The home page covers the company intro, services, why choose us, vision and mission, clients and partners, a link to download the company profile, and a contact form that sends to the company email There is a projects page (about 10 projects with photos) where each project has its own page, and a certificates and accreditations page with images and PDF files The most important part for me is the admin panel. It should be in Arabic so the company team can edit texts, photos, projects, certificates and the company profile without a developer It needs an admin role and editor roles. An editor's change only goes live after the admin approves it. They can preview a change before publishing, roll back to any earlier version, and see a log of who changed what The site should be fast on mobile and SEO ready. Content and photos are ready I'd like to know the cost and timeline, how long support lasts after delivery, and what is and isn't included in the price, like hosting, domain and maintenance The budget is approximate and negotiable, please send your price and timeline
