Are the users going to trade with you or it's going to be another P2P platform?
If you're simply offering a similar platform to Paxful and LB, It's going to be hard to bring users unless your project has something that your competitors haven't and I don't think that simply saying that you have better support will do the trick.
I dont think they can create any other P2P as good as LocalBitcoin itself. This p2p platform is already spread across the globe like fire and most of the people are using it since many years now. The trust rating for this platform is like 5 star and I have hardly seen any complain against this exchanger. They have escrow service of their own which is fully automated and can be trusted all the time. Whether you are a seller or buyer the system confirm the both sides first and then only it releases your escrow. This is actually a fun way to make p2p and I dont think there will be any other out there.
