I would be very hesitant to purchase any advertising package sold by the company you have joined. Many companies sell their own advertising package to increase their profits - whether their package does squat for the buyer.
Many bizopps use incremental sales to their distributors, charging for anything and everything, all the while knowing that they are profiting regardless whether their sales force is or not.
Managing your own advertising and marketing keeps you in control of the cost, and doing it little by little, you can adjust future purchases based on what works.
You'll need to test various methods in such a way that you can quantify what works vs. what didn't. Try a mix of both online and off-line marketing media and expand where you get the best ROI (Return on Investment).
