If you are doing it by hand, buy some Prima Amigo which is a heavy filling glaze and will last a while. Top it off with a wax or sealant.
Autoglym SRP should be ok too, although I've not used the new formula. Again topped off with a wax or sealant.
You can't really get scratch removal by hand without a jobby load of effort. I'll try and find a post DaveKG did on DW.
This will give you time to save up for a machine polisher
