Need help with designing my web page. Wordpress with the Letterpress theme

I am trying to design my web page with Wordpress. I have purchased the Letterpress theme and I understand alot of it but I am having some issues with the logo and some of the other features. If there is someone out there that could coach me through getting this set up I would be most appreciative. If it would be easier just to design it for me then I will chose that route also. I will most likely need help with the SEO also. Trying to learn !!!
