Haley T.United States
My name is Haley. I've always had a passion for writing and I just recently began blogging and looking into freelance writing. I honestly enjoy writing about any given topic, and I work really well with research writing. I also am great when it comes to proofreading and editing. I don't mind correcting other's mistakes. We all make them, right? I am a fairly new freelance writer but I have completed quite a few training programs and believe that I am ready to take on the job. I can meet deadlines without an issue as well. Writing is my passion and I take it very seriously. I hope that one day my writing will get me somewhere, and I believe that if I continue to put in the work it most definitely will!
