Since you are in hurry, K12 curriculum may be a good starting point. You can buy one subject or all of them. You can even do a different level for each subject such a 3rd grade math and 1st grade LA. Everything is planned and set up for you. K12 has placement tests to help you figure out which grade material to order. There are demo lessons to check and I believe there is a trial period as well.
There are quite a few families who use k12 curriculum and are happy with it. I've never used it though but then I like to mix and match material from different sources.
Here are a few of the things, which may be worth looking into. I use the material with DS5 or/and DS7.
- Singapore Math (placement test is available on their website)
- My Pals Are Here, Singapore science curriculum. We used it as an additional resource but I believe it would work nicely as a standalone curriculum
- All About Spelling
- CyberEd (may not be available at this point)

TAGMAX archive (if it's up) is a wonderful source of info.
The big problem is that there is so much available that it's very easy to get overwhelmed by all the choices. I think it's quite common that you buy what you think is the perfect material for your child and you only to realize that he or you don't care about it. BTDT
