As i'm not a team member, i'm in the glad position to talk freely:
There is the ren multichain github, with a how to to get the first steps going to possible be added as renasset and what communities can do own their own to get most of the groundwork done.
When looking at dgb (and at that point, you gotta ask them on how), they managed to get the bridge and all the ground work going by themselves.
I have no clue what you spent the 333 dash on, who took the money, or what they promised you will happen...but to my knowledge there is no "pay us x amount of moneyz and your coin/token gets added" thingy going on.
Now not to talk down on dash, i'd love to see rendash, but before talking about the upfront costs you had, might be good to say * what exactly * you paid for, and who gave you promised for * what * to happen.
