Dear Laura - I appreciate your edits. I like them! ;)

As you can imagine, this is very competitive position and I want to put my best piece of writing forward.  If you cannot already tell, this is my dream job. I have worked towards this for years.  

I aim to do another draft revised with your edits, and then some of my own improvements. The issue however is that I am crunched on time. Application is due midnight on Monday, and that means I will need some help over the weekend.  

My question to you is whether you are available this weekend? I will need someone who is prompt and responsive, so if you cannot do it, please point me to another colleague who would be available.  I appreciate your offer for editing it free of charge.  If we go to another draft (third/fourth,etc) I would be willing to pay you whatever your deem reasonable.  I wish we can communicate via email for faster response (?)  Please confirm your availability.

Thanks,

Talha
