B2B Tech Lead-Gen Cold Calling

VodaNow is a French company providing a QR code ordering system for beach clubs, pools and restaurants. We are looking to contact TPV/POS retailers in the Canary Islands regarding a partnership opportunity, and we need these calls conducted in Spanish on our behalf. We are looking to work with an established telesales or call centre company. Small agencies are welcome, but we are specifically seeking a business with a proven track record rather than a newly formed operation. A Spanish company based in Spain is strongly preferred, for both native accent and local time zone.
