We are a language discussion forum, not a proofreading service. If you post here, people may take a look and correct it or make suggestions. There are no guarantees that they will do this.
It make also take time before anyone does it, so posting something that requires urgent attention is not advisable. Allow people time- they are coming here in their free time out of interest.
Proofreading is a time-consuming activity, and if you need things done urgently, there are plenty of pay sites that will meet your needs.
