Dear Sir/Madam,

I need to write an email to cleaning service company and want to ask his Quotation and Services details. I want to invite them to servey my location for cleaning.

Please help to to write a professional letter.

Hi, syedluqman!

Since you know more than anyone else here about what you're wanting to ask, I would suggest that you post a draft here, without putting in any contact information.

If you do that, I'm sure that there will be those of us willing to come along and make suggestions to you as to how you might make improvements to it.

Thanks!
