Hiya,
Mac Safari user calling!
I really like the colours of your site - maybe it's because I love the colour purple?!
I take it you're using a MS Office Live site (i started with one of those when I first started out!). It's a good starting block but once you've learnt some more HTML or you have extra funds to get a graphic designer to re-design your site, you can easily upload HTML files to your page via MS office live (as you use IE7 it's easier for you than it was for me on a mac as MS office live never works on macs!!
anyway, enough about the design, I'm going to give some constructive criticism to your pages:
Home - I'm not too sure about "mission" and "objective" as titles, in fact I think the "mission" section is a bit out of place at the top of your page!! Have a go at re-writing your front section - Say something like "ABC Company provides....." or, even better, have questions on your site, like "Do you keep running out of time in the day to do the basic Admin work that needs carrying out? Do you need extra help around round the office? Don't despair - ABC Company can help you!" - hopefully that will help you. You can move your mission section a bit further down your page.
About Us - I'm going to agree with Diana on where you have two paragraphs before we get to read about you. Now, there are two ways around it - you can leave it like that; or you can split the page into two (by creating a new page or sub-page) where we meet the team. However, "My goal as a virtual assistant...." should read "Her goal as a Virtual Assistant..." - as you were writing about the third person in all previous paragraphs, it reads better; and IMO it's best to write in the third person anyway!
A Virtual Investment - you should make the font the same size - I noticed that some fonts in the table were HUGE and I couldn't make sense of what it is!! Even though I like the two column effect, I'm not too sure on it as a web page. It's worth reviewing, however it won't make that huge an impact.
I really like the
Services page - very different than having a basic list like other VA sites, yet we can still see what you do!
The
Rates page is also a good page - nothing else needs to be done here, you've done the core bit!
Contact - content is good, but make the contact form BESIDE the picture - there's a gap and IMO it's looks odd!
Not too sure about the
Project Request page - are you going to have a new page; and is it coming soon? If so, then just put "Page Under Construction" instead of "Place Content here" - it looks more professional. You could even have a roadworks sign, if you wish!
With regards to the <title> </title>, Jules has already gone over this with you but i totally agree with having your company name in there for
SEO purposes. How about having "ABC Company | Home >> Diary Management, Word Processing, Virtual Assistant" ? You could have something like "ABC Company | Home" (however, I have About << ABC Company if you want something different!)
Overall, the core content is there. Just a few more adjustments and you'll be there! However, it's worth mentioning that a site is a work in progress all the time - you'll never be 100% done - you'll always be adjusting bits every couple of weeks - i even today found myself changing some of the text to differentiate myself from a VA (i.e. advertise as Freelance offsite office support)....
Hope I helped and the best of luck!

Revamped the website AGAIN...LOL
. I made some modifications to my website. Your feedback is very much appreciated, especially from those with browsers other than IE7. 
and I'm getting nervous.
. I went back through and made sure my fonts were consistent where needed and I moved my Q&A next to Contact Us.
. Thank you for all your advise.
