Has anyone had much use of XMOD and Dynamic forms?

I wish to create a villa rental portal for owners.

Essentially I need to provide ways for apartment owners to:
1. Enter information about their villa - locations, details, prices (forms)
2. Manage their villas and activate them (pay me) and publish or not publish them
3. Manage the availability of the villa (??)
4. Enter their own paypal details to receive payments online
5. Review bookings that have been taken


I need customers to be able to:
1. search for villas by location, availability, size etc....
2. view villa information
3. book a villa and pay deposit.
4. review bookings and either finalise payment or cancel
5. post comments/reviews of villas


Overall app needs to do things like:
1. send confirmation emails.
2. send payment reminders and invoices
3. have featured properties

a basic outline of what is required....

CAn I use XMOD or formS to develope such an app ?

I'd like to utilise a bit of AJAX so that there is not continuous posting (something i noticed with forms demo)

thanks sebastian.
that is what i think as well...but i am trying to explore all other options before i start spending my life developing code.
thanks

Greg,

thanks for that
I think I am going to have to explore the options further

perhaps try and get a localhost version of these things to test.
