Direct Booking Website Development for Short Term Rental

I operate a single location short term rental. It is currently listed on Airbnb and VRBO. I would like to have a website designed for direct booking in addition to those two platforms. Key features: • Ease of use for guests I'd like something simple, with lots of pictures of the home and that is easily navigable by prospective guests. The fewer pages the better - Maybe a home page, a page with photos of the home and property, a page with house rules and terms maybe and then a booking page? I'm not sure the easiest design for this and will rely on your expertise and recommendations. • Booking calendar integration or communication with the other platforms Right now VRBO and Airbnb calendars are "linked" so that I can't end up with double bookings. I also have VRBO set to request only while Airbnb is set for instant booking. Guests visiting this site need to be able to see dates that are and are not available obviously. I'm looking for someone experienced who has done this type of website build in the past. I know nothing about the process or things like collecting the sales tax, etc, so I need someone with expertise in this. PRICE IS JUST A PLACEHOLDER - I don't have any solid numbers in mind.

AI/ML Client Communication Specialist

I’m looking for someone who can become the voice of our engineering team during the U.S. workday (9 AM-5 PM EST). You’ll hop on several video or phone calls with our American client, listen to the issues they raise about the software-development process, and respond on the spot with well-reasoned, technically sound guidance. Because the conversations often stray deep into AI/ML territory, advanced expertise in machine learning is mandatory. Your background in both web and backend development will also help you translate business pain points into practical engineering tasks the rest of the team can execute. Clear, confident English is absolutely essential—you’ll be expected to lead discussions, ask probing questions, and persuade stakeholders toward the best technical path forward. I already work with U.S. companies regularly, so the cadence is fast and direct; you should feel at home in that setting. Key deliverables each day: • Real-time participation in every scheduled client call • Concise written summary of each discussion (action items, decisions, blockers) sent within an hour after the meeting • Immediate escalation of any critical risk or requirement change to our internal Slack Success is measured by the client’s continued satisfaction, the accuracy of the information you relay, and the clarity of your written summaries. If you thrive on rapid-fire dialogue, enjoy bridging business and deep tech, and can remain on call throughout the EST workday, let’s get started.
