Wordpress Website Assistant

I own a podcast production agency called Podigy ---------- ---------- ). We create podcasts for the coaching industry and we are growing fast.

What we need:

1. Website development: we need new sections for our current site, and want to change the design structure a bit.
2. Website updates: each month we would like to add new elements and would need someone to update it for us.
3. Blog posts/case studies: we would like our blogs and case studies to be posted to the site each month
