Definitely a no no on the ads. Save this for a client that is running an information only portal type site and needs to make some money through advertising, not for you. It's just bad manners.
Although your code is valid, try to clean up the extra a bit. Use line breaks as little as possible. You are using them in some places, such as the contact page, to provide a margin (top or bottom). Do this instead with CSS. And although it's valid and perfectly legit, get rid of the empty paragraphs. Again, use your CSS.
The design is clean, albeit very very very simple.
And not that i'm to judge, but come on man, have some pride in what you do, if this is really what you want to do with your life, don't sell packages. It's cheap, impersonal, and takes all the fun and uniqueness out of being freelance.
If a client wants cheap, be cheap, you get what you pay for, but don't sacrifice your pride and skill-set just to please cheap individuals. If it's not your very best work, don't do it. Don't sell yourself short. Packages are a way to make easy money, but aside from the money, it does nothing for you. Freelancing and design definitely isn't for those who want to make millions, it's for those who pride themselves in their skills and never settling for less than the best of themselves.
Keep up the good work, but remember, it has taken you years to gain the skills you have, so don't let it be taken advantage of, mostly by yourself.
