Hi dude, are you using google translate to form your sentence 

"many" should "my"

"made acceptable graphic presentation"..what do you mean ? Did you make a power-point or something ?
or are you saying you just promote it

Anyway, as fare i know "intregration" is/means that they need to build the code to support the coin.( meaning they need to build the back-end software to support the coin algo )

you still need to pay for listing

yea  "intregration" could be pay now..but what about listing ?
