Hi... Long time osclass user, first time poster.

I’m using the Zara theme and have a custom script written to allow classified based on particular users, feed to another website. It’s time to update my site.
I’m wondering if there are any independent contractors who can provide plug-in updates, SEO, theme work and general site maintenance services?
Thanks 

I do not think single person that would do that, as if you do Seo, you probably do not do other things etc. Not sure, just opinion 
Regarding theme & plugin updates, custom work and maintenance work, you can contact [email protected]
