Yep that’s right 
You can either make me a temporary ftp account, or in most cases, you can take care of the ftp’ing.
If you have wordpress, you may need to upload a plugin for me to install, if you use static pages, you can just send me the files you’d like edited via email, and then upload them to your server.
If you use a CMS, you can make me a temp account there .
I will ftp for you if it’s nessasiry and you don’t know how to upload/edit files.
As for your first question, yep I can fix up your page, and offer you some seo suggestions.
