Hi there,
I would love to help you with installation of either yoast seo plugin or all in one seo plugin with their best confidguration as these are the two most highly recommended seo plugins around. Then I can help you with installation of the wordpress as well. For page speed that depends upon number of factors, plus that job in itself is not a quick fix takes alot of time and testing so couldn't be done in the budge that I have shared plus I have no idea about your website so I can't know what or how much work is required. So we could perhaps do that part as a new project after the first part is done.
Also adding google analatics is included in this bid.
Regards,
- Syed
