I am a freelance journalist and have graduated with a 2:2 BA (hons)in Journalism and English.
I understand that your needs for your website are to create blog posts that are child, toddler and baby related. Whilst I do not have a child myself, I am an aunt to a 1 year old and a cousin to a 6 & 8 year old who has to buy for them on a strict budget. I have also grown up on a budget and therefore have learnt many tips over the years in what to buy new, what to buy second hand, how to holiday on a budget, and so on and this is information that I feel would make excellent blog posts to support your website as well as pass on the information that I have gathered.
My current rate is £20 - £25 per blog post I write dependant on the length and the additional work required. for £111, I am willing to write 4 blog posts but will be happy to talk further about creating more.
