Thank you for the comment. Yes, this project is doable and it’s something we’d like to add to core as well, so we can offer a special deal to your client. He can have it sooner, and at a discount rate.
There are some important details we have to figure out (like email support). If you have thousands of people saving searches and the server needs to send thousands of emails at the same time, we have to think of a scalabale solution that can support this. These are just ideas on the spot.
The good news is that we have the technical knowledge to help build this. If interested in an offer, please email me at [email protected]
