Need Assistance in Contacting Spanish Speaking Customers in Mexico

I was give 5 sales leads in Mexico. I found the contact information for 3 of the companies online. I do not speak Spanish and tried to call these 3 customers in English and found most of them do not want to speak with me because I can't speak Spanish. I am looking for someone who speaks both English and Spanish to help me search for contact information for these 5 customers and contact these customers. I am willing to pay an initial fee for making the calls and if the calls generate sales, my company will pay you a big bonus.
