Regular Blog Post for an online matenrity dress shop

I'm looking for someone who can provide 3 blog posts a month for a maternity dress website. Need to be based around:
- particular dresses we sell
- seasonal fashion trends with a pregnancy twist
- general fashion tied into pregnancy
- pregnancy health/fitness
- pregnant celebrities
- all using our keywords (maternity dress, maternity office dress, maternity occasion dress, etc)
Our clients are mainly professional women who can afford to and want to still look smart, stylish and pretty during their pregnancy.
I was wondering if you can help.
Many thanks
