I'll be very honest, it would not be that difficult to create your own website once you have some samples and then broaden it from there. The market for HANDMADE urns, pet or otherwise, is one asking to be fulfilled. Ultimately, it all depends on how far you want to take this. You would be able to market to both the public and funeral industries(if you decide) and it is all a matter of branding and getting into a booth at your local funeral service convention. With technology being what it is, i wouldnt be surprised if you couldnt get several lead generators to direct traffic to a site once it is up and running.
I agree, that looks awesome. Doing some to sell on the side would be a good way to urn some extra cash
...you asked,brother. It can seem overwhelming at first, but you'd be surprised how many urn companies start out exactly as you are planning. I think you are proceeding in the proper fashion-start slow, you might not even want to go further. However, good luck and if you need further info, just ask.
