I'm writing a quotation and have to estimate a delivery date. My estimate is that we will make the delivery at January 1st. However, this will be impacted by when the project starts. It is in our interest to start as soon as possible and want to express this in a subtle way.
The delivery date is estimated 01.01.2015, but may be accelerated if the commencement of the project is earlier than 07.07.2014.
According to my good friend, google translate, the "delivery may be accelerated" is the proper way to express this. Google returns 62000 hits for this phrase, so I won't be the first to write it that way, however, I'm not so sure it's the best way. Also "commencement of the project is earlier than" feels a bit wrong. I would actually like to write accelerated there, but in that case I can't use accelerated in the first part..?
I don't want to write: "The delivery date will be impacted by the commencement date" as I want to focus on the positive (it can be done sooner but not later).
Any views on this?
