Audio specialist to edit some sound files

I need a Audio specialist to work and edit my sound file. I have a MP3 audio file thats about 1 hour/60 minutes long of a seminar that i have given and recorded. I need you to "delete" some sections of the audio and "insert" (3) other audio segments that i have recorded into the piece. They are shorter segments ( 25 seconds/ 4 minutes/ 2 minutes) I have all the times marked of when and where you need to do these things at. I just dont have the right producing software to do this. THe recordings that i have done are fairly good in that they sound pretty "natural" ....so that when you insert them they should sound good played with the "original " piece. BUT I would like you to 'Touch up" (if necessary) the 2 new recorded pieces so that the transitions sound as "natural" as possible when those sections are played....SO that it sounds like it was ALL recorded at the same time in the same place :) I WILL CHOOSE SOMEBODY QUICKLY AND END THIS POST EARLY.....I need this done ASAP..Bonus Points if you can start project right away...Please place a bid on this project. DO NOT BID THIS JOB UNLESS YOU ARE EXPERIENCED IN THIS TYPE OF WORK AND ARE CONFIDENT YOU CAN DO THIS TASK :)) Will result in Future Work
