I'm looking for realty script that will allow me to charge other agents and homebuyers to list their home(s), upload virtual tours
(or add links) and a few other options.......for a fee with
2check.com as a service provider for credit cards

I was recommended Realty Listings Manager (http://www.esvon.com/index.php?pg=products&subpg=p_cl_realty) from Esvon but want to hear if there are more alternatives ?
