@Yiannis, I didn't 'bash' or 'blame' anyone. I don't know what 'services' I should be looking for which is why I'm trying to hire someone to help me understand that. Also, your statement that "...offering a budget which is close to the monthly MoZ subscription..." is not accurate. I pay $99 a month for Moz, that is not close to $500.
@vadim, yeah I tried that recommended list section. No luck.
Of the 39 vendors in the SEO Consulting section;
1 - provides courses, not consulting
5 - do not provide any pricing information
33 - have pricing that starts at a minimum of $1,000 a month
Local Search, 23
1 - does web design
1 - does project based only starting at $1000
3 - no pricing provided
18 - pricing that starts at a minimum of $1,000 a month
At this point it doesn't appear there are any firms that offer monthly retainer services for our budget.
