Crazy how you can contradict yourself so many times...
Here let me give you some advise for your next posts.
Clearly you are new to the whole forum thing but usually on forums stuff that include sales are based around trust. To trust someone the seller needs either a lot of vouches or have donated a significant amount of money to the forum. Since Rune-Server does not allow showing off high amount of donations vouches are your way to go. If you cannot provide any of these then the person with a better reputation should pay afterwards after seeing if the service is real or not especially with these large sums of money or you can add to your post that you are willing to use a reputable/staff member as a middle man.
Second of all your post here is really dodgy since you barely provide any public info and say "DM me for more info" since I do not see a reason to why you cannot post the same info in this thread. Any info you share with people here in dms can be leaked anyways so better off sharing it in the thread as well unless you have things you're hiding and don't want others to call you out on a scam. Transparency is the key to sales which you don't do a good job at it seeing your account is brand new and you are selling a service for $1.5k then $1k then $500 seems super legit right?
Last but not least... why are you bashing people for being suspicious since you barely provided any relevant information to your "legit business"? You sound really annoyed when replying showing a horrible attitude for someone whos brand new on the forums starting off with a horrible reputation already.
Conclusion: This service sounded really interesting but would much rather buy crack from a homeless guy under a bridge than buy any services from you.
