Dear to whom it may concern, (unless you know for certain that the addressee is a man, most formal letter will do this as to not cause offense)

I am writing to apply for the post of layout designer (In reality if the job application has used layout designer as the title of the role stick to this, this title sounds professional enough so keep it in)as advertised on July 12^th  on your website. I have 15 years’ experience as a DTP specialist in a printing company within the IT department. (I’d only used I have worked if you’re naming the company specifically. In which case you say something along the lines of, I have worked for (said company) for (number of years) in the role of (role title)).  This position is would be a (adjective) opportunity for me, as I have expanded myrelevant experience and skills. (In application letters the language is formal and confident so I suppose and I think are normally avoided)

As you can see from my enclosed CV, I am a qualified engineer and (Keep I believe. Most natives are taught not to use ‘I think’ in this scenario) have an excellent standard of technical and professional skills required for this role. My current salary is $6,000 a year. 

I realize that the closing date for applications was last Tuesday, but I hope you will still consider my application. I will be available for interview at any time, apart <a href="x-apple-data-detectors://3" dir="ltr" x-apple-data-detectors="true" x-apple-data-detectors-type="calendar-event" x-apple-data-detectors-result="3" style="color: rgb(0, 0, 0); text-decoration: underline; -webkit-text-decoration-color: rgba(0, 0, 0, 0.258824);">July 22</a>^{<a href="x-apple-data-detectors://3" dir="ltr" x-apple-data-detectors="true" x-apple-data-detectors-type="calendar-event" x-apple-data-detectors-result="3" style="color: rgb(0, 0, 0); text-decoration: underline; -webkit-text-decoration-color: rgba(0, 0, 0, 0.258824);">nd</a>}<a href="x-apple-data-detectors://3" dir="ltr" x-apple-data-detectors="true" x-apple-data-detectors-type="calendar-event" x-apple-data-detectors-result="3" style="color: rgb(0, 0, 0); text-decoration: underline; -webkit-text-decoration-color: rgba(0, 0, 0, 0.258824);"> to July 23</a>^{<a href="x-apple-data-detectors://3" dir="ltr" x-apple-data-detectors="true" x-apple-data-detectors-type="calendar-event" x-apple-data-detectors-result="3" style="color: rgb(0, 0, 0); text-decoration: underline; -webkit-text-decoration-color: rgba(0, 0, 0, 0.258824);">rd</a>} (keep your date formatting the same as previously used) when I have arranged a vacation (holiday?) in Poland. (Depends Vacation = American Holiday = British.
