Dear Mr/Ms,
I would like to apply for the job you posted.
I know that I do not have any previous jobs(experience) on freelancer and it would be difficult for start to find someone to hire me, but i just opened my profile. I see that my college it is not worth for this job so im not mentioning it :)
This king of job is what I like to do, because the most of my time I spend on computer and I am also interested in this topics and i read a lot of this so this is going to be nothing but just an ordinary thing.
I can assure you that your project would be finished in very short time.
I look forward to meeting with you and discussing my qualifications in more detail.
Sincerely,
