Hi, I have read your project description, and I'd like to assure you of my availability and ability to complete this research assignment in the best possible manner. I am an experienced market researcher/lead generator professional and have a lot of experience under my belt in handling such projects. Given my experience and expertise, I can guarantee some excellent info on medical specialists as per your specifications.
Most importantly, I am not a run of the mill freelancer and I only take up projects where I am sure that I can work and match or even exceed customer expectation, a fact that can be easily verified from the recommendations that I have received from my previous clients.
Overall, it'd be an honor to be associated with you on this project, and I look forward to hearing from you on this.
[I have a Masters from Georgia Tech, and experience of working in some of the top firms in the Silicon Valley]
