Upgrade an existing research website (XML eXist-db XQuery)

I currently have a simple, small prototype website which contains academic research on the inquisition [login to view URL] I need to do upgrades to the site which includes XML, XQUERY, XPATH and HTML/CSS and Ajax. I am both a medieval research and software developer. The site is very modular and the data is well architected, although the site is not very pretty yet. I want to upgrade the look and feel through Bootstrap and add a few pages. I have designed the enhancements, but I do not have the time to get them implemented in the next 30 days (the deadline). Therefore I am looking for a developer who can jump into my existing simple website built on the eXist-db platform to deploy the enhancements. The site is already functional, but needs enhancements as follows: -install and apply Bootstrap CSS/HTML to existing pages (quite trivial) -update the code for two existing page templates -create code for three new pages which display lists (requires Ajax do dynamically update lists) -create code for a new page for users to download various files -plug in the eXist search function for full text search of the XML database The project must be finished by June 7. Once the enhancements are done, the application will be moved to the official digital humanities platform of the French National Research Center (CNRS). The current prototype took a developer 30 hours to build in 2017. I expect the enhancements will take no more than 20 hours - the architecture is very simple. Project technical specifications: The webservice is a NoSQL database and application platform: eXist-db ([login to view URL]). The documents are well-structured XML files and JPGs. All web code is written in XQuery (using XPath to get data). Documents are NOT processed through XSLT - the webpages are generated directly by XQuery and Xpath.
