It sounds like you got a lot of the same answers...you can't potty train a child! You can sometimes potty train yourself, but not a child. They will not do it unless they are ready and it has to be pretty much on their terms. Here is the deal with the potty-training time-frame...typically at about 18 months there is a period of time when a child may start to show curiosity about the potty. This window is typically short (I don't know if yours has passed for you or is coming soon). If you don't respond to this curiosity in a consistent manner (dropping everything to take her potty every time she says she has to even if it has only been 5 minutes since the last time and sitting with her for 15-20 unproductive minutes on the toilet) if you don't do these things, you will miss the window. If you miss the window, you are relegated to be an observer until 3 or so, when they will decide for themselves to become trained.
When my first child hit the window, I attacked it. She was good becaue she would pee in the bathtub every time the water would run. As soon as I realized this, I would run the water, put her feet in and then pick her up and put her on the potty. I would praise the heck out of her and tell her "good job going potty!" I said this so she would get the connection that what she was doing was actually "going potty" so she would have a feeling to connect to the words (very important concept, could you imagine if someone sat you in a cockpit and told you to fly the plane! I kind of think that is how kids feel because they don't know what exactly "go potty" means). OK, enough with the dumb analogies...my daughter also hated to be wet. There were a few days that we put big girl panties on her (blues clues were her favorite so we got those) and I told her not to tinkle on Blue puppy. She did a few times, but then she would get upset. It only took a few days and then she would run to the bathroom and call for me. (I went through a lot of Resolve carpet cleaner those few days). I also gave her M&Ms or mini marshmallows when she would go in the potty. She was trained by her second birthday.
I missed the window with my second daughter. She didn't get trained until 3 1/2 despite my constantly working with her.
I caught that window with my son thank goodness, but we were in the middle of moving and he regressed a little, but was trained by 2 1/2.
I hope some of this information will be helpful for you. Oh, I just re-read that you are working full-time, so it will be very difficult to get her trained unless whoever is watching her during the day is as dilligent at the training as you. You may be able to use it to your advantage though if you tell her to, "show your teacher how you go potty like a big girl."
Good luck with your endeavors! Oh, and consider getting someone in to help you clean your house once a week and take some of the pressure off yourself...you think it is tough to juggle responsibilities with one child, a house and a job...two is twice the challenge, but we are all here for you!
