Social Site Submissions

I need someone to post my website pages and press releases to several social sites daily. I can give you the login info for about 60 or more I'm signed up for. You need to create as many u.s. social sites as possible. 300 is better than 200. Must be very experienced in this, or I will get kicked off of sites as I have in the past. Currently I have about 150 press releases on free press release and maybe 40-50 site pages (and growing). We were submitting 1/3 of each daily and rotating. I will need proof of submissions emailed daily. This is an ongoing project that will grow to article and other mass submissions. I represent people in U.S. tax matters. Google "killer IRS" Please respond with your expertise, by telling me what you think my site should do for social submitting, how often, and what you propose I should do, and for how much. People with a high rating only!
