Custom Link Exchange project (600 legitimate links)

We have two websites, and we want to promote each one, by exchanging links with other websites, with related content. We are only interested to exchange links with other websites, that are listed on [login to view URL] Directory, and/or Yahoo directory (not yahoo search results) We would provide you two separate pop mail boxes on those domains to you. Using appropriate pop mail box, you will then contact those websites in related categories ([login to view URL] - ministries, churches, charity, nonprofits), and insurance-wisdiom - insurance agencies, insurance companies, insurance references , insurance organizations. You would ask each website webmaster, if they would like to exchange links, and email them a link to our website. Once each one emails you back the information, that link was placed, and URL, where it is placed. You would then place a link back on our website, and email them the URL, where their link is placed. If no response from certain webmasters, you would then email them again, maybe at different mailbox or same, until you get a response. We must get 600 total links back, 300 for [login to view URL] and 300 for [login to view URL], each link must come from website that is listed in Yahoo Directory or [login to view URL] Directory. We are willing to pay 30% upfront, if you have good feedback, otherwise we will only pay when project is done. If the project is not done, or done in part, less than 600 links total, we will pay proportionately. Must have good english, and be able to write letters, We will give directions on how to post links back on our website using Joomla, easy, no designing experience necessary. Thank you for attention. Project is estimated to take 30 to 90 days, part time.
