I would change the template (it's ugly, old and confusing). If you don't want to spend money in one, search for free e-commerce templates.
Also, rewrite the products description as they are copy-paste from other sites.
As for seo services, if i don't know how to do it, outsource it! Look in fiverr or similar sites, search right here in MMD, there are lots of people that can help you.
