Dear Christine,
We have discussed the project and we have made good progress till now.But i have to tell you that we can't accept your decision that we should put the project off .If so we would waste a lot of momey and we can't face all the stuff in the firm.Although we find many difficulties now ,either in money or in workers,we can try our best to smooth all of them and fulfill the project in time.So we have to plan the project more carefully You are the person who take the responsibility for this project,if there is a delay,you have to take full responsibility,please handle it well.
We have considered all points thoroughly,and given the amount exceed the real cost during our budget,If you arrrange it properly,there is no reason to increase the budget,please try you best to sovel it,I believe that you can do it very well.
yours truly
