Obstacle Course Race Map update

Im looking to find a illustrator that can take over and create future course maps for our Obstacle Course Race events based on our already established style. Attached is the map from our event in May we need the same type of map for our race in June. I can send you the .ai Illustrator file which has all of the elements and vector artwork, as well as the Font type used. What we'll need from you is to download the new high resolution google map satellite images from the new venue (I can assist if you require help with this) and then to work with the race coordinator to create the new course map. The style and layout of the new map should match this one, all we need changing is the satellite image, the course route line and the obstacles placement and order. The new map will ONLY be the SPRINT 3mile red course (not the CHALLENGE or TIER 1 green 9mile and 12mile) and there will be less obstacles, so it will be simplified but we will require a zoomed, close up of the event area. Please let me know how much this will cost, please bear in mind you will have the editable .ai file and not be creating from scratch. However, with the nature of the project, there are likely to be a few revisions toward the race deadline (June 16th) so your quote should reflect how much you are willing modify and update. Thanks Tom
