Wix real estate website (Wix Expert required)

Hello,
I need for my Wix Real estate website to create :
1-A search fonctionality on the homepage, so users can return the right list of propertiers from the database.
2- A specific page for posting an add (property description, details, pictures,...) that would then feed the database.
3- Filter properties based on price and return resutls (display 0 property found, in case of no result)
3-Also activate the paypal fonctionality for payment once the add is posted.

Thanks for your proposal!

Best regards,
Mustafa
