The software is not available for purchasing. I've followed all the available links and although they lead to the official website, a 404 page is displayed instead which could mean one thing: the software was discontinued. Afterwards, I visit the official website with hope to find it, but if you check the All Products page, you will see that MacFreelance is nowhere to be found.
You should contact the developers of the application: http://www.macwareinc.com/macware-about-us/contact-us.html
