I don't get this. Are you trying to sell a $12000 website to a petstore?
It sounds like you are a little too inexperienced for this project.
What exactly is the the client after? A Blog, website, CMS, e-commerce solution?
If the client has specific requirements then don't try to bullshit and offer him WP.
You need to be clear on what he wants.
If it can be achieved with WP then knock up a quick mock up and show him.
Offer him a discount for the WP option.
If you can out-source (NOT FIVERR) then do it. You can use The Marketplace or Hire a Freelancer sections.
If this is beyond your capabilities then be honest with him and tell him you can introduce him to somebody that can do it.
(There are people here who may be willing to work with you, just make a post in the JV section)
Good Luck
