I'm not going to write anything for you but may I suggest that you should propose your websites to various websites like coindesk,coinbuzz and cointelegraph.
They might be kind enough for a press release. I doubt they'll just give you a press release, you may need to pay and it since they're mainstream websites, they possibly going to cost a lot. It will generate a substantial amount of visitors to your website however, so look into that.
Thank you for your suggestion. I am aware of these sites and I know that they will probably cost a lot. That's why i am seeking for other websites. But I agree. They are mainstream websites that will generate a lot of traffic so I will get in contact with them too to see their rates.
