Use treats to teach the dog the basic commands. Sliced hot dogs are inexpensive and all dogs like them. Slice them into nickel sized pieces, and keep them in a pack around your waist for easy access. Have your Mastiff sit for you, and reward her when she is sitting calmly, close to you and looking up into your eyes. This is called "focused attention." Keep repeating the Sit" command until she does this correctly without you having to push her back end down. If she is hesitating to go down, raise your hand with the treat up over her head and slowly push it towards her back end. This will force her nose up and back, and make her much more likely to sit on her own.
