Yes, people will be interested - I say this because there are numerous websites that already offer this service. Take a look at Houzz for example.
As for models, almost all the known online models would work: advertising, affiliates, commission, fermium etc...
I’ve successfully helped over 320 startups and entrepreneurs and would be happy to help you. After scheduling a call please send additional details and I’ll be happy to provide you with more value during the call.

Good luck
