Virtual Assistant in Europe

I am looking for someone intelligent having nice communication skills who can help us reach to our clients. We have 2 products and we wanna sell in European Market. We already have the Clients list, we are just looking for someone who can help us contact with client (as we don't know their language, some clients speaks French and some Spanish and some Germany). Planning to hire 1-2 Individuals (based on the language they know to communicate) Basically you have to introduce our company to them and by talking to them need to find out the purchase department manager contact details (Email, etc.). So I can connect with them. Also for some specific clients if I need your help in further conversation (We can decide a nominal and best price). I have more than 500 Customers list. This job will take 1-2 Months, as we can't call all of them in 1 day. We will call them as per your comfort and timings. The best one with the least price/connect will have the job. Thanks !
