Hi there,
I understand you want someone to promote your blog by inserting links to your website in pieces published elsewhere. Is that correct? That can be done, but it'd be better to have blog posts on your own website. That draws traffic, and reduces bounce rate. It'll also make your site appear helpful and human, rather than promotional or business-oriented.
I do not do direct promotion for clients. However, if you want posts to publish on your own website, I'd be happy to write on the subject for you. Dental health is something we all should be educated about, and at least in India, I think information on the subject is rather scarce. In my experience, dentists don't ask most people to floss either - which can cause problems later.
I charge 1 INR per word, so the project amount would cover (roughly) 3 blog posts of 300 words each. Message me, and we can discuss this project further.
Regards,
Priya
