I'd say put some images, maybe proofs of payment to keep readers interested. Also, ussually most successfull websites tend to have a lighter background, not that your color wont work, its just that lighter colors are easier on the eyes (well for me atleast). As well, a nice simple, clean, not too fancy template would make your blog much more attractive.
If you want to keep the green colour scheme , this might be a good choice:

Of course, there are many other you can pick from the same website.
