I need some advice on which CMS to use for a new project I am starting. It will be a babysitting website that will have paid membership for both the babysitters and the people seeking babysitters. There will be onetime and subscription plans. I want the signup process to be as easy and quick as possible, to make it simpler and more appealing. I am thinking that I could retrofit a classifieds CMS to work for this, as long as it allows for paid memberships, as it seems like a fairly similar setup.

Thanks in advance!!
