Don't sell it cheap and regret later if the project become a successful. I think you must discuss with your team members first if you have any, before making any deal with your project.

Dear, colleagues                                                                      UPDATE: 24/07/2018

Newbies have hard times and this forum is not an exception. This way, newbies cannot participate in signature campaigns. However, there are some exceptions to the rule.
In this topic I will post bounties with signatures for the newbies. And even though the pay is very high, this will be a true training for them, and not the spam post for maintaining activity.
