CV, Cover Letter and competency based questions

I am looking for someone to help me with London based graduate job applications in the field of finance. The current job includes the writing of one cover letter (500-800 words) editing my CV and completing the competency based questions for one job application. If I am happy with your work I will assign to you the tuning of my answers to all subsequent applications I submit. Please submit bids only for the current project (1 cover letter, 1 CV, 1 set of competency based questions) and include in your PM to me roughly how much subsequent applications will cost (I assume it will be less as most of the work will be done during this project). I expect that the freelancers will have excellent written skills and good understanding of the UK graduate market. He/she will be required to research the qualifications I have and the companies I want to apply for and to present me in the most favorable way. Payments will be release after completing each stage of the project. Please include in your PM details about your previous experience with similar projects.
