SEO and marketing specialists

I need someone with great English who:

can understand training videos
can write great articles/content
knows how to build great _non spammy_ links
works hard and doesn't make excuses

my site already ranks well but it can definitely go higher for some keywords. Let me know about work you've done before as that will be what I will make a big part of my decision upon

Also let me know if you have any great SEO software and how you intend to put it to use

Part time 20 hours / week work
