why can't you ask tantrick or creative ? You don't need to ask for a reference off a trade supplier all you need do is tell whoever wants a reference these are people you trade with, and these are their details. All they will then do is write to them and ask how long have you traded with them, how much do you spend and do you pay your bills on time - that is all a trade reference is. Your bank reference is even less - usually contains this line : We do not believe 'x' woudl enter into a commitment they could not fulfill.
Personal references from people you know will be longer and more in depth perhaps, but a trade reference is showing how you trade and cannot say much more than above, while a personal reference has a much wider range of things to include.
As said before they are only after a view on you, renting property to people is always a risk and even people with the best references are not always reliable. You only need to worry if you can't get an acceptable bank reference. Even if you can't get a good reference you can always put up a bigger deposit against default, not ideal but gets you round it and then your trading history will help you.
