    Anne Balke

    Consultant/Writer/Researcher

    United States - Last active: 13 hours ago - Tests: 6 - Portfolio: 21

    Recognized top 5% oDesk contractors. I have the skills and experience necessary to complete any of the following jobs: complex research, writing, editing, basic websites, business consulting (online marketing strategies for small businesses) or other similar projects. One of my specialties is helping people develop well-written informational content that brings organic and natural traffic to their sites. I provide writing, editing and formatting services for online website content. [Note - if you are trying to view my actual website from my profile, I am in the process of changing hosting providers so my site is temporarily unavailable. As a result, some of the links in my odesk profile many not be working. Just ask if you need to see more work samples and I will get them to you.] I am fortunate to have a gift with writing and truly enjoy it. Over my lifetime I have met many people with brilliant ideas and thoughts who struggle with getting them into writing in a way that effectively conveys the message. I have a passion for helping people take their ideas and putting words on paper so that the ideas can be shared with others. There is a great sense of satisfaction that I get when a client tells me “that’s exactly what I wanted to say!” Although I have not been formally hired as a writer until recently, I have an extensive writing history. I am conscientious and thorough in all that I do, often going above and beyond employer expectations. I have an inner passion for knowledge and answers. If I don't know something, want new information or want to learn how to do something, I do whatever is necessary to find the answers. My preferred jobs are advanced Research and Writing projects that require someone with great attention to detail and an analytical approach to finding information, not just "collecting data." {Don't get me wrong, I enjoy the data collection process, but typically simple research jobs don't pay equivalent to my experience & expertise.} Outside of freelance work as a writer, I provide business consulting, web design and online marketing services for small businesses, "from one small business owner, to another." As an entrepreneur who has been through the struggles of learning how to succeed when resources were limited, I understand what it is like to build a small business from the ground up. My formal training is in Psychology and this background gives me a unique perspective on the world of marketing and behavior. I have been a work-at-home mother since 2002 and absolutely love the freedom that being self employed provides. Let me be upfront - if you are looking for someone to work at "outsourcer rates" or to provide any work that is unethical or "black hat," then I am not that person. But if you are looking for a person who will provide HIGH QUALITY and ORIGINAL work, completed by someone with both an attention to detail and a creative mind, then that's me. I stand by all my work and won't work on anything that I wouldn't be proud to put my name on. As a business consultant, it is my job to Research and Find Solutions for my clients, as well as find information relevant for their business/industry. As a web/internet consultant, with knowledge of how content and keywords affect search engine results, I have a full understanding that there is "much more to be found" beyond the first Google results pages. On the educational level, I have a Master's Degree "plus" in Counseling Psychology from a school that was extremely research oriented, preparing students for Doctoral Programs. Not only did the regular coursework require routine research and report writing, but the program included completion of a Master's Thesis. I also have an undergraduate minor in statistics. Prior to becoming a freelancer, I have over twenty years of experience working with children in social and school settings. My specialty was working with children with emotional and learning disabilities. As the Director of a Youth Shelter, I also have experience supervising and managing teams. In 2002, after 20 years in the corporate world, working full time "plus," I made the decisision to change focus. With these New Priorities I started down the path of being a "work from home mother" (WAHM) and home business owner. "Enjoy Life Enterprises" is the umbrella for all of my entrepreneurial and freelance endeavors. Because I am completely self-employed, I have flexibility in the hours that I can provide, based upon what is required. I am located in the United States (North Carolina) and can be reached by email or if you are US based, we can talk by phone. I have also set up a Skype account if you are outside of the US.
