Hi,
As an MBA graduate with 7 years of experience on using MS Office ( started with office 2007, presently working on Outlook 2013), I believe that I am more than qualified to work for your assignment.
I would like to work for your project as a trial basis to evaluate whether or not I am a good fit.
If you like my task , you can pay me and I will continue working for you. If, however, you are not satisfied with my job, I will not charge you anything and we can happily part ways.
Regards,
Shatarup.
MBA.
