Hello Juan Carlos,
Thank you for your question.
Please send your designs to design[at]memotrek.com and we will provide you with a detailed quotation.
Regarding the taxes you have to pay on the import to Peru, I think the following website might be helpful:

I am sorry, my Spanish is not very good, so I could not get far into the details.
We ship the goods with DHL or UPS, which will take only a few days. The carrier will help you through the clearance process.
Best Regards,
Katja
