Well, my immigration people told me the cost for I-140 is 2700 dollars something (with a little increase of the amount). It's not 700 dollars, so that's why I want to wait for a little bit.
-Nonsense! probably they ask you to pay the lawyer fee also.
Read this USCIS website about I-140 filing fee:

8老师,再问一下,如果我现在决定先交140, 过几个月,140还没批,但485排期到了,我可以继续交485吗 (without the new approved 140)?
-Yes.
谢谢!
