RestAPI / CSV / iCal data conversion

I am running a vacation rental website which currently has limited connectivity options for 3rd party properties to be displayed on the site. My currently website can only take an iCal link for individual properties availability and pricing from 3rd parties.

I have a couple of new property suppliers who have a RestAPI to provide property availability and pricing along with all the property details.

So as a temporary / low cost solution, I am look for someone to setup / create a middleware solution which can query the API, get each individual property’s availability, price and details, and allow this information to be accessible via an iCal link (for availability and price) and csv (for property details).

I have attached an example for reference, but any specific questions please do ask.

I do not know how much something like this could cost or ongoing costs, I am looking for this to be a low cost temporary solution until I am able to fund a full website update. So appreciate any feedback.

Thanks
