To get to the point… one important way to build trust from your readers would be to provide value-based content that your audience can benefit from. Providing this worthwhile information will create a spellbinding magnetism causing your audience to develop a thirst for more. This action alone will build trust and in turn your readers will begin to like you and look up to you as an authority in your niche. 

I have an idea: in my opinion, upline,the company, the product etc… are just 20% of your success pro in building mlm. and attitude and educations is 80% of your success road. you can just do your guidline, be positive and make a positive mental believes in your selling group. consistency and believe is most important keys in your industry. fear, but do it!!!
The real selling point for MLMs is that distributors can make money in two different ways. The first is money made from commissions from direct selling to consumers. And the second way to make money with an MLM is from the commissions made from sales of distributors below you in the pyramid (these are sometimes referred to as recruits or downline distributors).
Use a tool. You should not be explaining everything about your opportunity or whatever it is you have to sell over the phone, point them to a video, sizzle call, event in their area, anything but you try to explain it all over the phone. You can say “The first step to see if this is even a fit for you is to watch our short overview video at ________________”
