It would be appreciated if I was chosen for your project as I am a perfect candidate for the requirements that you have stated. I have been writing as a freelance writer since four years now. I assure you quality work and timely submission of tasks. Your terms and conditions are my top priority and they will be kept in mind during work. I can write on any niche, be it health, shopping, technical, travel, product review or anything, I am sure I can write on it and I can start working immediately. I can only tell the rates once I know what type of work you exactly have (My rates are extremely negotiable so they won't be a problem). About the sample article, freelancer does not allow me to attach a file in the bid proposal.
Thank You.
