Congratulations on getting your first website up, what an exciting accomplishment!
I agree with much of the feedback you've received, especially the advice to make the site 'warmer'.
Try this:
See if you can put yourself in the shoes of a potential client and what they would expect to see when they come to a website to hire YOU. What are they questions they have, what kind of colors do they expect to see, what are the objections they might raise. You want to answer all of that for them.
Another thing I might suggest:
Are you trying to convince them they need a virtual assistant or that they should hire YOU as their virtual assistant.
I see on your main page that you are telling them WHY they should hire a VA. I hope that by the time they get to your website (via google search, referrals, ads, etc) that they already know they NEED a VA and now they need to figure out who they want to hire. I suggest you assume they already want to hire a VA and use your main page to convince them why they should hire you and what you have to offer them.
Hope that helps too
