Sound Editor for Dialogue

We have completed a short film (14 minutes) and are just about ready to submit to festivals, the first being SXSW, and all of the sound has been mixed except 5 lines of off camera dialogue (no lip synch issues!) that have been recorded but need cleaning up- compression, filters etc. This was a very low budget but well made short. It is well shot, well acted, impactful and will hopefully get some attention, as we are also shopping a feature project, but we have one problem: the whole movie was mistakenly outputted as one merged file, so we cannot fix individual components. The editor is not a sound editor and we are trying to add just a few lines of important dialogue- again, that do not require any lipsynch, and he is having trouble getting the levels and sound quality right. This is a fast, easy job for even a somewhat novice sound editor. There is a deadline of 8/28 for SXSW so we need this done before then, ideally by 8/23 with a little wiggle room. You will get IMDB, credit, and hopefully we will work again on a fully paid basis as we move into our first feature film later this year
