Congrats on what looks to be a very cool new product. I think the correct way to sell these on Pinside is by setting up a business tied to your account and adding them as a product to your storefront. I've been selling daughterboards through the Pinside market since the feature was first added - it's very easy. That will get you CC processing via Stripe which is much less expensive than PayPal for moving money - especially international transactions. You may also want to look in to creating a multi-currency account at wise.com (a UK company, I believe) - their cross-currency fees are well below any other options.
