Hi AynCG,
Our team does not do custom installations of All in One SEO Pack Pro, but we have detailed instructions on how to install the plugin on our site here.
The Pro version of All in One SEO Pack has an XML Sitemaps module which will help you create a sitemap for search engines. You won’t need to add any other sitemap plugin to your site.
You don’t need to have any knowledge of coding or html in order to use the Pro version. If you do run into any issues you can contact the developers via the Premium Support Forums.
There is support for WPML on All in One SEO Pack Pro, again if you run into any problems you can contact the developers for support.
Here is our contact form if you have any further questions.
Thanks,
Nina
