请高手帮翻译下～千万不要用软件直译～翻译的好我再送50分～
以下：
“好的～
大致是这样的～
我先画出单色草稿给你看,可以修改3次,超过三次仍不满意就终止合作,不收任何费用,如果草图通过就先支付一半费用给我,然后彩图完成后会发小尺寸的样稿给你,也可以修改三次,3次后仍不满意就终止合作,一半费用不会退回,如果彩图通过则在发完整尺寸大图前支付剩下一半费用,到帐后42小时内发图给你～
另外从动笔到彩图完成大概需要一个20天到1个月左右,具体时间可以再讨论～
有疑问可以再讨论哦～”

好了.内容翻译完了,词和表达都核了一遍,应该能准确表达你的意思.
All right!
The general process is:
I'll draw a monochrome draft for you at first.You can ask me to modify it three times.If you still feel unsatisfied then,we just stop the work and you don't need to pay.If you accept it,you should pay me half of the remuneration.Then I'll send you a smaller sample when I finish the full-colour work.At that time,you have another three times to ask for modification as well.If you can't accept the full-colour draft,we stop the work,but you'll not get back the paid money.If you consider the work is OK,you should pay the other half of remuneration and I'll send you the whole-size work within 42 hours after I receive the money.
By the way,I'd like to notice that it will cost 20 days to about a month to complete the whole process.Details can be discussed later.
Any questions are welcomed.Best wishes!
