Hi Gia,
Congratulations on your site and for spending the time to learn how to create it yourself!
I had no trouble loading the image and video on the home page - although I did get a bit of a shock when the music started (I had my speakers turned up loud!). I'm thinking maybe you're selling yourself short by not listing these website services to your clients too!
I notice that you have mixed fonts on your site, and in some cases on the same page ('Project Management', 'General Administrative Services' and 'Pricing'). I would suggest changing all text on your site to a san sarif font such as Arial, as it is easier to read onscreen (as opposed to a sarif font such as Times, which is easier to read in print).
Overall, great job! You've done well.
Cheers,
Kirsty.
