vps reselling and direct admin

[jnet]

I am not in vps business so I might start just with reselling vps
the vpses I want to resell have not control panels so I need to have one installed. How direct admin will sell me control panel for this purpose?
with the view of the fact that I will start with small scale How can I add a diret admin to the vps I resell so that my whole vps does not become expense?

This is urgent as I have an inquiry in hand . I prefer direct admin even though there is one more control panel I am considering

Please let me know

thanks
