Hello,
I am happy to have discovered your work ad, even though you have not provided a lot of information to work with. With that in mind, I'll try to keep my cover letter brief and just present myself as a good fit for the position.
In terms of work experience, I am a relatively new writer, keen to tackle a wide array of different subjects and fields with my work. That being said, I do a whole lot of research in my free time, whether it's hours and hours of informative videos and documentaries on YouTube or books on various topics. I like to believe I possess the ability to quickly and efficiently research virtually any topic and I'm also excellent at selecting key information and describing it in an enticing way.
In terms of creativity, I try to stay up-to-date and constantly refresh and update my personal vocabulary with definitions, phrases and idioms that I pick up from the various stuff that I watch or read. I try to maintain a personal style of writing, but am able to adapt to specific requirements when necessary.
I value deadlines and assignment objectives to the highest extent and if I ever run into trouble or have questions and suggestions I always form them in a rational and reasoned way. I'm sure we won't have any trouble getting on the same page.
Please contact me via freelancer.com if you have any questions or are interested in my proposal.
All the best,
Šarūnas
