I would recommend you start googling vaginal birth, homebirth, and unassisted birth after caesarean. I would be looking for lots of statistics and studies. You might find some help on the ICAN website. I know there are other support sites out there for VBACing women, but I don't know them, as I've never had a c-section. I would want to be in tip-top shape, exercising regularly, and eating very healthy.
I'll just be honest here and say that if it was me, I would really want a midwife there for a VBA2C. I'm the type who tested myself first before I went that next step. I had two highly interventive births in the hospital. The next birth I went natural, stayed home as long as possible, and had the natural birth in hospital. This taught me that I could give birth without any interventions, that my body wasn't broken. I then went on to have not one but two homebirths with midwives assisting, even though I knew about UC. This taught me that I really could do it by myself. The midwives did very little, and what they did do I could do myself or my husband could. And then I had my UCs. For me, this constant testing out was necessary to my own peace of mind to ensure I was being as safe as possible. I still got prenatal care, 20-week ultrasound, etc. That was important to me too. I have said that if this baby is breech (which I have no history of, this is just one of my contingencies), I want a midwife at the birth. I know not everyone is having a large family that would enable them to test themselves and their abilities in this manner, but it worked for me.
And I say all this only to give you my own point of view and what I would do if I were in your circumstances. I don't judge you at all, if you go ahead and have a UC, just because I wouldn't. It is based on my own comfort level, and that's very personal. I don't think that you won't or can't have a beautiful successful UC right off the bat, in fact, I imagine the odds are in your favor. I will congratulate you and support you unless you reveal something healthwise that could factually put you and/or baby in danger, and then I would advise you toward safety measures, which could include professional care.
And just because I watched this recently, it was fresh in my mind, so here's the link to a video of exactly your situation. A VBA2C. Good luck to you on your journey.
