I have a property portal ([url removed, login to view]) in production mode.
This portal runs on Joomla 1.0. Subscription to this portal and posting of property advertisements to this portal is currently free.
Moving forward into 2010, I like to upgrade my portal to be a pay-per-use site=>users can still sign up for free BUT if they were to advertise their properties on my site, they will have to pay for each listing posted. The price to pay for each listing can change as per the duration of each listing and position of the listings.
I am also thinking of allowing the users to buy credits to use for their advertising. (i.e. 20 credits for 20 listings, 50 credits for 50 listings)
One more thing, can i have the flexibility to charge for subscription to my portal.
Please advise feasibility, costs, effort and schedule.
I am willing to share with you my source code and database for your analysis if required.
