Two page website.
One realtime search box (searches data in database as you type, and displays table of results)
5 x nested combo boxes where the users selection of the first combo box, affects the contents of the second combo box etc
Results are displayed as a table of results
Super clean minimalistic design - interest more in the function than a pretty page.
Prefer a simple approach that can be updated by the owner of the page
Will develop & install on a Digital Ocean VPS
