I haven't earned 3K or more merits but at the same time I think that my post quality is high. If you struggle to fill the Hero spot and it's okay to offer you alternative payroll in this case (pardon me if it's not okay), then here is my offer:
I'll join this campaign with the following payroll: 3.75 USD per post ((Merit payroll $5 + Hero Payroll 2.5) / devided by 2 = 3.75).

Rank: Hero Member
Alternative choice (optional): $3.75 per post
Merit earned in the last 120 days: 205
