I like the clean look of your site but, at first glance, it's not clear who you are and what you're trying to say. I'm not sure that someone would "get" who you are and what exactly you're offering. You have a great testimonial from one of your clients and it could be placed differently to draw more attention it. I hope this helps!
Although I have not read it through for spelling mistakes, I really like your site. It is easy to read and maneuvers very well. What a great feeling to design your own website. Kudos to you.
I was really confused as to what you can do for me. You are using valuable space for the images when in fact you should be telling me what you can do for me. If I were looking for a VA and landed on your home page I do not know that I would continue.
Maybe move your copy that is down on the bottom to the top.
"Clear your desk without having to commit to a full-time employee." - This should be displayed prominently as it states the WIIFM factor.
The rest of the pages at first glance look good but you need to get people to want to visit them for those to be effective.
Loved your website! I did the opposite of you - in March arrived out West and now have our services available from our motor home we just purchased (that is why my website is going to be under revision for awhile with all the changes) -- so I appreciate your work -- Good luck!
