I did something similar in my 50's, but sadly, with no previous musical background, it wasn't a good plan for me. Now I just work on them. I started out with a lower priced Romanian instrument and a synthetic bow. That was a good choice. The teachers that I had at the time thought that both the instrument and bow were fine for what I was doing. I bought mine at a local shop.
The disadvantage of buying online, is that you don't really have any idea of what the set-up is going to be like. If you buy from a local luthier, they should check everything before they sell it to you, and if there is a problem, you can take it back to them.
If someone brings me a violin that they bought online, and wants some work done on it, they pay full price.
