Brita, your statergy looks fine, articles and blog submissions are good in it's own way. First you try all the off page stratergy, after some days, you will only come to know the best technique .Have patience and analyse your website traffic on everyday basis.
I emphasize on content focused Press release, article submissions, blog articles; are they help in improving the site rank?
Your SEO strategies are mostly fine but if I were you, I would stop submitting content to article submission sites. They tend to be sometimes spammy and has duplicate content. Focus more on creating online interactions like in social media, forums and even blog commenting.
I suggest not to do article submission as it can be considered as spammy. If you really want to increase your traffic and ranking do submit your article on blog and share them with your friends and followers on social networks. It will help you to make your website more viral and you will get natural backlinks from your friends and followers too.
You can also add your websites to online review platforms like Yelp and ask clients to write some good reviews about it. Don't do mass article submission or you will have negative impact. Better write some good articles and find relevant blogs to publish them.
