I'm sure others on here will be along with good advice. I had never done any before other than a day with an excellent trainer working on my oldest dog--he spent several hours in the salon which left its mark on him so that psychologically he was not comfortable with any of it beyond combing. It made my (grooming) life much easier when I bought a proper table and H frame. I also started by doing very little at a time and have built up so that now I can 'finish' a dog, but I keep on top of their coats now instead of trying to trim them once a month, or whatever. I was really pleased that my young dog, Bean, has grown into a very patient and helpful boy on the table. Although he still hates his nails being done, I have lots of high value treats next to me and whenever we manage to clip one he gets lots of quiet praise, a treat and big hugs. He knows he's achieved something good too and I wait till he is settled again before I tackle another nail.
Although my oldest dog is still very hard work I've got him to the point where he will now accept a few minutes at a time without becoming anxious. I'm teaching him to stretch the time out a bit by swapping jobs--so if he starts to get upset with trimming ears, we go back to the thing he likes (combing his back and stripping out dead undercoat). I also hold him in a hug so he feels secure(ish) rather than hang onto an appendage.
As it happens I have a very young puppy now and I am training her from the outset. She likes to sleep on my lap so I have a baby brush (not a comb) next to me on my desk and a pair of scissors. I stroke her feet so she is used to me holding them. She gets no more than half a dozen licks of the baby brush and I find I can trim her ears and nails while she is dozing.
You don't say what age your girl is or what breed, but are you trying to do too much all at once? I found that expecting any of my dogs to just sit there and let me get on with it was totally unfair and unrealistic, and the more I tried to get through it the more unhappy and pressured they felt--that's when the turning round, hiding paws etc starts. It sounds like you need to get to the basics--no more than a minute or two, make sure she is tired out properly beforehand, have some really impressive treats at hand for good behaviour and lots of praise for being a good girl and be ready to stop doing what YOU want to do to reassure and settle her. Not easy, I know, but if you are stressed she will be buzzing from that.
