This is not the job for you, I'd seriously suggest you stop wasting your time on this site and find something you're good at doing. This isn't your skillset and it shows.
If you do continue you need 1 of these 2 things (you have neither right now):
Amazingly well written, detailed reviews that blow people away.
skills to get your reviews ranked top 3 in google for their keyword.
I just checked and your Burton 2013 Custom X review isn't even IN google search results 4 days after you posted it on your website.
Typically a partnership would mean you bring something to the table. You don't bring anything to the table at this point so why should someone do the hard work for you and give you a cut of the profits.
Prove your model first. Get your reviews ranked highly on google. Get traffic to your website. Get some GOOD reviews on your site. Get real income coming in from the ad revenue.
Only then should you be asking other people to do your work for you because you'll be bringing something to the table other than a slow loading wordpress website that could be duplicated in under a day.
