Source contact information from internet

Hello, I am looking for someone to collect information for me. I need a list of email addresses of people who work in specific job roles in Australia. It should be fairly easy to find from the internet e.g. linkedin. All I need is firstname, lastname, job title, company and email address. Please quote per 1000 valid contacts. Please note I am looking for bespoke collected contacts - please don't respond if you are only going to supply data from a previously collected database. From past experience I am looking for someone to go out and freshly collect these contacts for me. I want valid email addresses only. We will be contacting all of the people on the list, so if there are too many email addresses that bounce, we will be coming back to you for more (I accept that there will always be a small proportion of emails that don't work - just so long as there aren't lots!) We have a regular need for this type of work, so I'm looking for a trustworthy, diligent, accurate and hard worker. I'm more interested in this than anything else. Someone who is accurate and reliable is the most important thing. For the right person this would lead to a long term working relationship. It would be helpful if you could indicate your level of spoken English. We conduct telephone surveys too so someone with excellent (I mean sounds like a US/UK/Aus native) spoken English would be a bonus. But this is not essential - please bid anyway if your English is ok.
