The software Tonelib JAM is an alternative to Rocksmith and is on sale right now (50% off). You can load psarc-files (CLDCs) into the software and have the notes charted as tab, notes or 3D synced to the backing track. Software can also be used for FREE even after the 30 day trial you can still use the software. You just have to wait 15s until you can use the software (similar to Reaper after the trial period).

Reviewing the code will be another hurdle for you. If you don't stay on top of this you will end up with an expensive POS. Maybe your friend can just do the code reviews for a cut? Otherwise, try something like pullrequest.com (code review as a service). Source: almost 3 years ago
