Hello
My name is Yusely, I'm an experienced Joomla/Virtuemart developer and also spanish is my native language so I can help you setup your website.
I'd like to clarify the job is only for installation and configuration of the extensions you mentioned. If you need custom development, that would require a ETA and pricing.
Please check my profile for references, I've done about every kind of Virtuemart customization on different versions of Joomla.
Thank you for your consideration and let me know if you have any questions.
Best regards,
Yusely
