Virtual assistant

Our Web Development company is looking for a part time virtual assistant for lead generation for our sales force. At this point it will be a part time position until we figure out what markets to target. It will pay $20 US dollars a week and as we grow we will increase the requirement to a full time position.
The job consists on using Yelp, Yellow Pages, Local Yahoo, Craigslist, Manta, Google to look up businesses in the US that need improvement on the current website or don't have a website or their website is not mobile friendly. Specifics on the lead search will change to accommodate what works best for our company.
The current requirement is 50 leads per day Monday to Friday delivered via email on excel file and the requirement will increase as we build our sales force.
