Sites to exchange +1s

I would like to promote my G+ page. What services should I use to exchange readers? That means,
where I can +1 one's page, and he/she will +1 mine in response?

 

it will be black hat technique..better to do manually ...

 

Thanks for reply... what do you mean by Black Hat Technique?

I understand that this is not the most right way, but it should be able to give results fast

 

Do not do +1 or likes exchange. Any exchange thing in SEO is considered black hat.

 

Thanks for your reply, but you still haven't explained what Black Hat means in SEO. Could you please?
