Signing up for adwords would have nothing to do with getting sandboxed.
The ONLY success in google google rankings, is backlinks. If you have no backlinks, you will be not be seen. I suggest submitting your site to directories, or getting a paid directory submit from people on digitalpoint forum. It's worth the money.
However your site WILL get sandboxed if you submit your site to too many directories, as google will see your site as spam.
It takes a long time, but work on getting backlinks with anchor text that you want your site to rank high in, and that will lead you to success.
