How challenging is it to build a custom order approval module?

We’re exploring launching a new customer approval process similar to the sites below. So after customers place an order, our artists can upload their artwork and the customers can log back in to approve or ask for revisions.

I imagine this is a custom module build? Can someone chime in on how difficult this is to build, time, and cost? A ballpark would be greatly appreciated. Thanks!

Hello @Growth101 ,

Yes this is a custom module.
It is hosted on subdomain and it is working with webhooks. Mean whenever an order is placed it sends the data order details to the artist and performs other actions.

For a cost and time estimate you can drop me an email.

Thanks
