Hi, thanks for inviting me to bid on your project.
I'd be happy to write one article a month for you. I'll be honest, photography is not an area I am completely familiar with, however, I have relatives in the business so I can appreciate the quality and value a professional photographer can provide. I've got a lot of experience with researching, I go to a lot of effort to make sure my work goes beyond fluffy filler.
I work best when I know your specific needs. If you can provide a list of 12 article titles, for example, I can work through them (in a specified order or as I select - it's up to you). Do you have a preferred word count and specific SEO keywords to include? I find that approximately 400 or so words is effective - long enough to say something but not so long that the audience switches off.
Would I be ghost-writing as you, or would it be unattributed? I don't mind either here, but if it's ghostwriting then I'll need to see some samples of your own writing to impersonate your tone.
This proposal is more questions than answers, I know, but I can never propose to solve your problem without knowing more about it. Best of luck in finding the right freelancer.
