OK guys so im not really skilled at this wanted to keep it brief and simple so tell me what you guys think, thankss

It sounds good to me but maybe add some more personal information like where you went to school
Hope this helps

perhaps it would be best to put "at your earliest convenience" at the end to show your politeness and courtesy. Maybe Sincerely yours, at the end, I don't know. Sincerely is okay too, I guess, but I like sincerely yours.

The words in red mean that you have to add the phrases. but , I am also diligent and able to multitask in a busy environment and exceed deadlines (correlative conjuction: not only...but also)

or and other -this part seems awkward. Revise.

I believe the following:
'...both orally and in writing, I am diligent and able to multitask in a busy environment and exceed deadlines; hence I am confident that I am the perfect candidate for the job.'

would be better if put like this:
'...both in oral and in written but I am also able to multitask in a busy environment in a diligent way while managing deadlines. I am therefore confident that I would be a perfect candidate for this job.'

I think it is a bit more clear.

thanks sounds a bit clearer
