Thommus Rhodes, Variant – big mess

Hello. I’m a newbie and I need help finishing my homepage. I paid one person to do it but unfortunately I got totally screwed. ?? Yay.. nay… :/ He did something and then told it was ready. Then I saw the page and wasn’t happy because he hadn’t done what I wanted. And then told me he’s not feeling doing it anymore. Okay.. so I have lost my money and now have to finish my homepage on my own. But the way he has made it is such a mess and I don’t understand a thing about it. On WordPress Editor I got nothing to change or edit because there is nothing to change or edit, everywhere stands blank spaces.. just “Add new” buttons to create something, except Testimonials what I added by myself today.. So far so good… *rolls eyes* But still on the homepage you see many things. Where the hell are they?
So I saw something what leaded me to Variant Thommus Rhodes.. So I got it that he used something named like that to build my page, but it’s such a mess and it’s impossible to add plugins and widgets there.. Doesnt seem logical at all for me. I only know how to edit texts there and then when I edit them some of the main menu links unactivate (by unactivate I mean that when you click on some stuff on the menu then it doesnt bring you anymore to the selected topic). What the hell? Help please…

I just want to add simple things, like HappyForms contact form next to Google Maps Location. Impossible.. spent hours today figuring out things.. Nothing, zero… Then I would like to change services Icons.. and some other little things. But I dont come to a clue… Im so tired of it and I think of shutting it down. ?? Cause I feel big dissapointment and have lost money.
