For last three years I have been working as a press release writer and submitter. I have a list of free press release sites that contains 50+ sites like PRlog, 1888pressrelease, online pr nesws, pr-inside, i-newswire etc. I am able to submit press release manually there. I will take less than four days to complete the task. After getting all the links together, I'll send you the report in a excell sheet.
