Only a Couple of content issues I see: "So for example, if our website obtained a sudden increase in traffic during your advertising period, your site will be benefited too" - "Will benefit too", would sound better "Therefore if you are interested we strongly advise you to send our team an e-mail ASAP" - Therefore, if you are interested, we strongly advise you send our team an e-mail ASAP" (not that big of a deal). The site works good, all buttons seem fine on my end.
Great buttons, mate! I really like your site. It will help some peoples to use beautiful twitter button on their sites.. Keep rock!
nice buttons, but I would recommend changing the twitter favicon to something more unique than the default.
