Contact List Building for Software Company

Hi, I'm looking for a VA to help build a business list of companies to call for my software business, collecting contact details of business owners. The businesses I want to contact are smaller food and beverage manufacturers worldwide but initially in the western half of the USA. This is going to be a long term, part time gig depending on quality of work I get back and also if we are a good fit in terms of communication. Please type unicorn in the top of your reply to confirm you read the message in detail. For the gig, how many records can I expect to get back and how long is the turnaround roughly? I have been combining information from InfoUSA and [login to view URL] to get the info I need, but if you have a better method I'm happy to use that.
