Can we work together?

Hi,  
   
 I hope all is well with you.  
   
 I'm contacting you on behalf of a large digital marketing agency and I would like to discuss guest posting opportunities with you. We have a sizable pool of clients to our name and so as a result, we have the ability to post multiple times on a given site which could lead to a profitable future partnership?  
 
I am looking to discuss costs with you. In terms of price, we would be looking to post for $50, however, we would be interested in posting around 4 a month.  
  
 It would be great to strike up a discussion on this and I would be happy to provide examples of our work and our company information at your request.   
 
Kind Regards 
 
Jay Worton 
 
PS: Apologies if you have received a similar email from us - it might be because you have more than one site.
