Offer for a linkback

Google Webmaster guidelines say that links in sponsored posts should be no follow and it should be explicitly specified in the post that you are paid for writing that post. But as far as I know, if you say them that you allow only no follow links, they will withdraw their offer.

Not many people ( except those who receive huge traffic from google and have adsense ) follow the no-follow rule. So, it is for you to decide what to do with the offer. 

I have been getting few offers to write sponsored posts these days though I haven't taken them seriously but I would really like to now what are the cons or conquences of writing these posts. Any advice while transacting with these guys and what is the average amount that should be quoted for writing a normal post for them? It will be really helpful if anyone can provide any info regarding this. 

About blogging ethics, if you mention in the post that you have been padi for it, then in my opinion it would be fine...

I think adding line breaks in your reply on an ipad is impossible... though not too sure
