Original Rock/Blues Guitar Instrumentals - Mix ok?

Hi,
I recently joined the site and have uploaded 6 new guitar instrumental mp3s in a Rock/Blues style. I would appreciate any comments re the mix e.g. overall quality, balance, sound stage and radio ready quality.
Feedback tells me that my mixes are too hot and sound distorted on some systems and, despite my best efforts, that they are nowhere near radio ready quality.
Is there a 'rule of thumb' for mixing tracks for a wide range of low/hi fi systems and mobile phones/ipods etc? Can anyone out there offer a low cost stem mastering service that keeps the track punch, depth and volume, without the severe 'Radio 2 style' compression?
