A video, like snginc suggested, is a nice idea but you should put the sales page in text also.
If you make a video, make sure the total time of the video is there.
If I feel the video can be too long I close it down and move on. I like it when it is straight to the point.
If there is some text underneath the video I skim it to see the great lines and if it catches my attention AND my interest, then I watch the whole video and read the whole text.
Put the essential text above the fold. So make the video small enough for us to see the headline of your text.
Busy people, cynical people and bitter people (who have been burned by marketers), will move quickly to the text to get the idea AND also your warranties and the refund policy (in your case it is free)
You can put the full refund "logo" (with the amount of days) or in you case, the free logo in it at the right of the video or text.
Here is a suggestion that could help you get more conversion:
1- Offer tips and tricks to newbies to start using those cash kits
2- Offer tips and tricks to make the most of the cash kits once the customers are comfortable enough.
Even if those are included with the cash kits, having this mentioned in your landing page will help you get more clients especially newbies that need someone to hold them by the hand or that need someone to guide them.
They will feel safer and they will feel they get more from the purchase.
You can always sell them other stuff later on down the line. Once they see how it works and earn some cash, they will be more inclined to buy to maximise their profit.
So mentioning you give away some of your tricks and tips to make the most of your cash kits, help you to brand yourself as a marketer that sell marketing stuff AND help the clients move forward in life.
So this way you sell yourself, your time AND your cash kits.
You will get more emails this way as well.
Also, anything that obviously make the customers feel safe should be visible right away. This will make more people inclined in buying.
