Dear Sir,
Am writing to request your evaluation of my latest curriculum vitae and forwarding to john for new Opportunity in Australia services shop. Would you be so kind as to write a letter of recommendation to what may well become my future employer? I know you’re very familiar with my work, and especially the many professional development activities we’ve been involved in over the past six years. I would will be grateful to know your opinion on this matter of critical importance to my career. I thank you in advance for your help.
Yours faithfully
***
and forwarding to john for new Opportunity in Australia services shop I'm not sure what you mean by this. Do you want your boss to forward it to John? Or are you just asking for advice on your CV?
If you want him to do it - "and that you forward it to John regarding the new opportunity in the Australian services shop."
if you just want comments "as I intend to send it to John regarding the opportunity in the Australian services shop."
