I need an advance level virtual assistant to do lead generation and data entry

Hello, I am looking for an advanced level virtual assistant to do lead generation and data entry for a project I'm working on. Specifically, I need the virtual assistant to perform data mining for the project, although other lead generation techniques (such as google search, website research, collecting emails and business information) may also be an option. The duration of the job has not been specified, but the budget is estimated to be a one time fee. I am looking for someone who is experienced in this type of work and can deliver the results I need quickly and efficiently. Please let me know if you are interested and can help me with this project. Thank you.
