I guess you are paying in your own token and not in any liquid asset (such as BTC, ETH etc.) ?!
Please give a brief note on that - thanks in advance.
If someone asks for payment instead of wanting to join our team I can offer only our own tokens at this moment
Well in that case it will hard for you to find one.
I also an advertiser myself and can help you to advertise in my group with your project. but if you paid only tokens only the project can only be benifited with that and not the advertiser and promoters. give a proper payment ETH or BTC is enough.
Or if you want to pay in tiken you should make a bounty instead.
