Hi, this sounds like a fascinating project and would love to win this job, improving my own knowledge of online marketing.
The writing and researching will be no problem so please get in touch.
I'm eager to win some projects on Freelancer and win long-term clients and strong reviews, as I've recently returned to Freelancing.
I can guarantee commitment to the project, and I have all the access to the systems you mentioned.
Hope to hear more from you!
Ade @ GRS
