A little of a tip, its more about how confident and reassuring you sound over lying.
They will ask you your income, projected income. If you said the business was open for 2 years, they will ask what your income was then
If you tell them you do online sales they will ask what you gross, and what you expect to gross by end of the year.
If you "sound" like a legit business you will get approved.
(Selling 5-10k wont do it - I know someone that said something along that and they were told that they are to small...)
