Blog Writer - SEO - Long Term

I've got $200 in the monthly SEO budget. For that monthly sum, I'd like to get bids on how many 250 word blog posts you can post for me on other real estate related blogs (i.e. mortgage, realty, home repair, home inspection, etc.) I'll provide the email script you'll use when emailing the various blog owners. The email will ask the prospective blog owners if they would allow a guest post from me, providing them with free content in exchange for a link back my main website. They will be invited to guest post to my main blog site for a reciprocal link, or guest post one of my other blogs sites for a three way link, if they wish. Your job will to be to: 1.) Email blog owners 2.) Write and send the blogs to the blog owners willing to participate. 3.) Make sure they have posted the blogs, and record the URLs for me. 4.) Receive and post their blogs on my site, if they elect to do so. In addition, I'd also like two 250 word blogs/per month written directly for my main blog site. I have many sources of content for you to utilize/re-write, so researching will be minimal. The winning bidder will have an excellent grasp of the English language, experience posting blogs and has a good work ethic. I'll start out with a one month trial. If things go well, I'd defiantly like to make it a long term arrangement.
