I need someone to run my company blog

Hello, I run a business called Morse Toad. We are a messaging service that allows you communicate via the medium of chocolate and photos.
I need a blog writer to produce 1 blog per week, potentially two. I have a spreadsheet with a list of blog ideas with their theme, title, target product, purpose and level of importance.
The aim is to provide good content relevant to our service, but not direct sales. Sign up forms and calls to action will be added at the base where needed.
The content must contain the relevant keywords. The tone of voice should be fun, quirky, humourous. Morse Toad is a pun, and has a logo of a toad in a top hat. All writing should stem from that.

To begin with, I would like someone to write 3 blogs from the list provided, so please quote for just three. If successful, then I will ask for the next three and so on.
Applicants must also be able to add imagery to the blog that compliments the subject matter.
Thanks Dicky
