Writers for self-development website - English

Hi! I´m building website for self-development and I´m looking for writers to provide contents.
You can write about almost everything that is related to self-development (Spirituality, Career, Relationships, Motivation, Meditation, Fear, etc) but the articles should be very specific, inspirational and call to action.
Here are 2 examples: instead of writing about "Creativity" write something like "5 ways to explore creativity through writing". Instead of "Benefits of meditation" I would prefer "Which is the best meditation practice for you".

I´m not looking for someone that would be able to write about all this areas. You should have practical knowledge in the area you are writing about.

Articles should be in English (native speaker) and can have between 300 to 800 words depending on the subject. I would prefer if articles would include a picture.

Proposals should include:
-Portfolio in this area
-Tittle of the article you would write
-Nr. of words
-Price for this trial article
-Price for a pack of 3 additional articles
-Timings

Thank you
