I find the whole SEO thing complicated and a bit

I find the whole SEO thing complicated and a bit of a minefield. I like the idea of using a special SEO plugin to help, but even with that the task is huge. I have considered getting help.

I think this is a bit of a stupid question but here goes;
If I hired a freelancer to do SEO on my site could I limit their access to just the SEO plugin? This is where it gets a bit complicated as the content and pages have SEO options with them as well. I just don't want to hand over full admin access to a freelancer who I don't know.

Any ideas please?
