Hello,
I have gone through your requirements for development of a property listing website for users and agencies.
I can get a quality, bug free and attractive website built because I have experience of developing many property listing websites each having unique functionality of buying, selling and renting properties, using custom PHP as base language.
Similarly we can develop your website with same functionality in congruence with your idea. Based on our experience designer will provide you with an interactive and innovative UI and UX design for the landing page as well as property listing.
Some main features in the website will be content pages, property listing with search tab and filters, user specific user panel, details page with image gallery, chat feature, social media integration, and contact form etc.
