Modern Responsive Website Development -- 2

I’m ready to overhaul SJ Digital Service’s online presence, starting with a sleek, fully responsive website built with clean custom HTML, CSS and JavaScript. The site must look and perform flawlessly across devices, convey trust to international prospects and collect leads through an easy-to-use contact form.

I’d like you to outline the smartest roadmap—from first mock-ups all the way to launch—and advise when we should layer in supporting activities such as Google Ads, Meta campaigns, ongoing social content, branding refinements or WordPress blogs (if they prove useful later).

To keep expectations clear, please send:
• A milestone-based timeline (design, development, testing, hand-off).
• A list of concrete deliverables: UI/UX designs, fully coded pages, contact form with validation and spam protection, on-page SEO essentials, deployment instructions and brief user guide.
• Acceptance criteria for each milestone.
• Your recommended tool stack and any libraries or frameworks you’d rely on.
• An estimated cost breakdown by milestone so I can plan cash flow.

Once the core site goes live and meets the agreed acceptance tests, we can expand into the wider digital marketing, ad management, graphic design and animation tasks outlined in my brief—so please indicate how your team could scale into those areas afterward.

Clarity, reliability and modern code quality are the main things I’ll judge success by. I’m looking forward to your structured proposal.
