No, the only included shiping providers are USPS, UPS and Fedex.
to create your own shipping rules using ecart, make sure the power store files are at the root of the Dreamweaver site.
There are not any tutorials at this time for creating the shipping rules, you just need to edit the eCart object using eCart and create the rules on the shipping tab. If you have specific questions on how to create a certain rule, please let me know.
