Maintain a website and also make a new website

I am seeking an experienced web developer to both maintain an existing static site as well as design and build a new site from scratch. The existing site requires minor ongoing updates and enhancements to keep content fresh and optimized. For the new project, I have a creative concept that needs to be brought to life through an appealing and intuitive user interface. Responsibilities will include selecting an appropriate platform, implementing a responsive design, and developing pages with dynamic sections for things like blogs, galleries and customer testimonials. Strong HTML, CSS and JavaScript skills are essential to craft polished, lightweight sites that display beautifully across devices. Usability and accessibility should also be top priorities. Once complete, the developer will provide training on content management before handing over ongoing upkeep. Potential applicants should have a proven track record of delivering high-quality digital solutions that meet objectives and deadlines. A keen eye for design aesthetics combined with technical acumen will be valued. Examples of past work demonstrating creativity and professional caliber of work are appreciated. Please provide hourly rates and anticipated timelines in your proposal. I look forward to reviewing submissions and launching these sites to support my growing brand.
