If I can give you advice, I did the same thing.  Found Thrive website templates. Found one I loved that had all the working parts of the website.  Tried to do it myself and spent HOURS and HOURS of wasted time.  Then I googled to see who works in Thrive templates, found this nice website developer and he did my site and showed me how to keep it current.  Anytime anything goes wrong with it, I call him.  I only paid less than half of what your freelancer told you.  Private message me and I'll share the contact I had.  He was wonderful to work with.
