DJ Ray,
I was preparing to respond using multiple quotes from your posts and with the intent of helping you but then I re-re-re-read your initial post and came to the conclusion that your are not deserving of any valuable advice, despite having already received valuable advice from Scott Hanna, Bill Kexel, ittigger, and others. Based on your stated behavior, you obviously think this craft is so simple, so pedestrian and requires so little talent and skill that you willingly and deservedly submit yourself to such circumstances. I wish you more.
The re-read quote that prompted me to reach that conclusion was,
You do not even have an honest appraisal of your own service. You claim to charge clients $300 for a similar gig yet even at that unprofitable level, you proceed to devalue it by working for 50% of your self professed value. By doing so, you did more than $150 dollars of damage to your alleged "business."
At those rates, I have little doubt that you are not operating an insured, profitable, legitimate dj service. If you have or claim to have a large music library, I doubt it is a legit, licensed/unleeched library. To legitimately posses the minimal tools of this craft requires more than you are charging.
You should heed what Scott has offered as his advice is valuable. He is apparently willing to facilitate and foster such discussions, probably with full hopes of changing your behavior for the better, specifically the bad behavior common to your kind of competition. Scott is obviously more tolerant and hopeful about you and the never-ending parade of past and future clones.
