note: first of all please dont start pm'ing asking to do my seo for me. i have a business (restaurant) in London, UK and was looking to start venturing out into takeaway deliveries, you know were people phone and order and i deliver to there homes like dominos. so i looked at keywords which i want to rank no.1 for, most had competition of only 1000, some even less, some more. so i posted an ad for seo expert to set up my seo for me as i dont know anything about seo. quite a few people contacted me and gave me prices. some said $300, $500 and i got one who said $2000. what i wanted to know is that is it worth paying for it and would they rank me at no.1, i know no one can guarantee but my KW have extremely low competition. also would these people just build backlinks or is there something more to it as well.
