Need Guest Posts on High PR & High DA Blogs on a Regular Basis

We need someone with a lot of experience in finding High PR & DA Blogs (Minimum PR of 5) for Guest Posting in our required niche and then get our guest posts published on these blogs with a dofollow link to our website. We are looking for quality guest posting services to real blogs with followers and social presence. Kindly do not apply if you are going to post to blog networks or low quality blogs. Ideally we would want someone who can write and then get the blog published. Only apply if you have past experience with such kind of work. Kindly provide me with your rate per guest post (with and without writing). We are looking for someone in the long term as we will have a continued requirement for guest posts and press releases. Kindly provide me with links to 5 of your best guest posts along with your application. I will disregard any applications without this.
