You are looking for advertisers,but can you prove that you have significant amount of traffic and
real active users on your website(which is going to launch).Probably not.
No advertiser will be that stupid to buy advertising in some newly started PTC platform with 0 active users.
People know that 99% of PTC sites are scams,can you offer something different and can you prove that you are legit?
Good luck with promoting your site,OP.
