Hi vicentemj,
Yes, if you can provide product details it can help us in choosing what suppliers can serve your needs best. :) We can filter the search to those that can send internationally, the system however, cannot choose by the type of shipping service yet. This info needs to be confirmed per supplier that you have chosen to work with.
I think it depends on the product being shipped, if the supplier will be willing to offer free shipping, as there are certain items that they will prefer to have delivery confirmation, and it will come with a price.
Let us know what you would like us to do. Cheers.
