It is difficult to find Services except you come on here. I am looking for a shilling manager for my project. Our offer depends on your team size and our payment is flexible $50 - $100 each 24 hours. We will pay advance before start of work every 24 hours. Dm me on bitcoin talk with existing works
What do you mean by shilling service? Shilling service is more sort of spamming service, and it will not help your project in the long term.
If you are really interested to promote your service on this forum, then my recommendation is that first you should make and publish an ANN on the relevant section of the forum. Then you may start a signature campaign for your project. It will be sustainable marketing and your project will get good coverage.
