Hi there people! I would like to ask for your generosity to look at this letter that I wrote to aplly for a job. Please feel free to correct anything you think that might not be well written as well as the structure. Thank you.

Thank you pieanne and abbie1948.

When finishing a formal letter, what´s the correct way to write it??? Your Faithfully/Your Sincerely or Yours Faithfully/Yours Sincerely. The difference is on the "s", are there both correct? Thanks.
