I have my reservations about sunnipath. In one fatwa, they allow calling on/invoking other than Allah, specifically dead people:

I have no idea about the other one you mentioned.
Try this one, the Islamic Online University, which is run by Dr Abu Ameenah Bilal Phillips:
http://islamiconlineuniversity.com/diploma/
If you want, you don't have to do a diploma, but can do single modules that you might want to do. Have a browse around all the parts of the site. I remember some other members here saying that you can do the modules at your own pace (but there is a limit). There is a course facilitator for each module if you have questions/need help, and you get a certificate. And it (the diploma and single modules from it) is all free.
You can also do a BA in Islamic Studies, but that's not free.
Perhaps other members may also have some good suggestions.
