Hi Adam
Thank you for your recent letter. How are you ? I hope you are very well. I'm writing to you because I want to talk you about looking for a new job.
At the beginning of the summer I was boring about a lot of free time which I had. I wanted to taking a job, I needed some money. I was looking for some interesting advertisment on the internet. Three days later I found something special. The woman was looking for some help to her garden. I was really interested in, so I called to her. I meet with her in her house. She asked me about my age and why I was interested in advertisment. I said I like take care of plant and I have any job. She was very nice and she gave me this job. At the job interview you must smile. You should be polite and friendly. That's the key to the success!
I look forward to hearing from you soon.

Best wishes

Proszę o wyłapanie błędów.

I'm writing to you because I want to 'talk' (lepiej uzyj slowo 'tell') you about looking for a new job.
At the beginning of the summer I was 'boring' (zla czesc mowy) 'about a lot of free time' (tego nie rozumiem, za bardzo po polsku - nie tlumacz slowo w slowo) which I had. I wanted to 'taking' (zle slowo, tutaj 'take') a job, I needed some money.
'The' (nie, tutaj 'a') woman was looking for some help 'to' (nie podoba mi sie to, lepiej 'for') her garden. I was really interested 'in' (nie rozumiem uzycia tego slowa tutaj), so I called 'to' (niepotrzebne slowo) her. I 'meet' (zly czas) with her in her house. She asked me about my age and why I was interested in (brak przedimka) advertisment. I said I like TO take care of 'plant' (ta jedna jedyna czy wiecej, tutaj l. mnoga jest potzebna) and I (daj tutaj modala) have any job.
That's the key to 'the' (niepotr) success!

Przypomnij sobie o uzywaniu przedimkow (a, an, the)...

Dziękuje za pomoc

Ja bym dał IN albo WITH her garden...
