I have a large text file that consists of 34,827 lines (6-digit numbers). You will need to pass all these lines to website's online form and copy&paste the output results to another text file, even the "NOT FOUND" records. The online form accepts only 15 lines at a time and about 10 queries (150 lines) per hour. For each 15 lines, you'll need to enter the captcha (4 letters). You'll need to change your IP to continue the process uninterruptedly. The job is lengthy - let me know your timeframe and cost, the optimal bidder will take this job. Payment - PayPal. - Fred
