Custom Booking Websites for Short Term and Mid Term Rentals

[Chris Hicks]

Hello everyone! I would like to build custom booking websites for owners of short and mid term rentals or just a website for marketing your properties. I have experience building websites from scratch with Python/JavaScript/HTML/CSS and also with WordPress. Would this be a service anyone would be interested in? What would you as the customer think is a reasonable price for a one time fee plus a monthly subscription fee to maintain/host the site and potentially provide SEO (Search Engine Optimization)? 

Also is there anything else you think would be cool to provide as a service with this business model? Thank you in advance!
