how much an SEO specialist or an SEO expert is getting paid?

[LonestarG]

the company that i am working as an SEO for them for 3 moths they are paying 12/hr to me. Behind the hard work i do, i have to do photoshop stuff, designing, but i can not do the content writing, i found a great content writer and they pay for it, the rest as far as goes to organic SEO and link building, social network, twitting, etc.. i do it my own + I give idea to designer, content writer, etcc I know SEO job is not web designing but i also helped the web desginer to build the website since i am good with HTML.
Now what i need to know is this work? or theyhave to pay me more? any info on that?> and they keep asking me where are results where SEO takes time!
They pushing me that they do not see results, meanwhile I can not do the magic for a website where it was really bad designed and spammed, is that possible?
