Hi,
Sure I can write Copy in English, well researched and with a flow that will guide the reader to perform a certain action. All steps of the sales process present and each supporting the next for a compelling read, the information fitting together with what your designers and managers require.
I have worked as a digital marketer for over 10 years, I can do from onsite SEO optimization to linkbuilding and the latest strategies to comply with the new google algorithms.
What is the topic about? I would require to know more about the product, the company and your competitors to know how much research would be necessary to do the required copy.
