Greetings "maxand99" As a native English speaker and fluent Spanish speaker who over the past 2 decades has lived over 10 years in 3 in Spanish-speaking countries including Spain (and travelled to half-dozen more) therefore, I assume I meet your requirements. My professional credentials / experience would allow me to converse comfortably with firms in most industries.
Pending a bit more detail, I believe I could successfully complete the project as I understand it. I have made PM contact should you wish to offer additional detail.
Alas, I must condition my offer on a couple of variables:
a) That the telephones to be called are "fixed" and not "cellular" telephones, as the cost for making the calls would be radically different due to the Spanish telephone structure.
b) That the information I obtain will not be used for any illegal purpose. I mention this, since if it is related to debt collection or something similar, each country has very specific laws about contacting places of employment.
c) That the "requirements" take into consideration the size of the firms (eg. if 15 people are 80% of the total employee list, one unhelpful receptionist would have a disproportionate impact than if the firm has 1000 employees!). In this vein, the "days" required would depend on the start date to take into consideration any weekends or Spanish holidays.
I await any communication you wish to provide.
