Extract 500 Ehibitor Details from Internet

Need company names, phone, fax, email (most important), address and contact name if possible for exhibitors at upcoming trade shows. This is a repeating project and we are currently doing it in batches of 500 names at a time. ** Please read the job description carefully. This is not a quick 10-15 minute email extraction that can be done with software (if it was we would do it ourselves as we have plenty of email extraction programs). Some of these lists will possibly work with email extraction programs, but most will require a series of steps (which we have listed below) and some basic hard work. We offer products and services to tradeshow exhibitors. We have specific shows we want to market to that are coming up in the near future, and we want their phone, fax and email addresses. There are two main types of lists here. Type A - Is a list of company names only. This lists will require searching the internet for that company's website and then going to the "Contact" page of the company's website and finding an email address, phone and fax (and address and contact person if they have it). Type B - Is a list that lists most of the information already and has a link directly to the company's website where you visit the "contact" page and get the email address. Type C - None of the below lists fit this category, but a lot of the lists we use have all details listed on the website (one click from the exhibitor list opens a new page with all info including email address). While none of the below shows have such lists others we will be posting in the future do. We are wanting to find a permanent person who can do all such work for us. The lists we want and the link where you can start are all type C above (the hardest). Links will be provided.
