I don't think its unusual to feel uncomfortable about childcare, particularly when your baby is so young and you have no family close by - this is one of the main reasons I took a year off work (although I know this is not possible for you).
We went to visit a couple of childminders and a couple of nurseries while I was still pregnant. We decided on a childminder as in all honestly we couldn't afford a nursery (here a childminder is about £10/£14 cheaper a day than a nursery, partly due to us just paying for hours that we use rather than full days, but also because the hourly fee is cheaper too) and it was also important to us that DD stayed in our village, mainly due to the fact that the childminder can take her to and from the school nursery once she is 3. My OH is a primary teacher and as a family, we are very keen for her to go to state nursery with a qualified nursery teacher (not stay on at a private nursery) once she is 3. There is a beautiful lovely nursery with a fab outdoor policy with an organic children's garden in the next town and if we were rich then maybe we would have put her there for a couple of years until she reached 3, but then if I was rich, I wouldn't have been going back to work!
There are benefits to all kinds of childcare, I think you've got to look at what you can afford, what is nearby to and practical for you and above all, use your instincts - if you're not comfortable with a nursery or childminder, don't touch them with a bargepole!
