I would include this kind of detail on the site somewhere, along with what the total 'size' of the wheel is, etc. Then people can calculate (via simulation, if not analytically) the house edge.
I see you're shuffling 450 0's and 3 1's. I saw one wheel where there were no 0's after the 3rd 1. I guess that means the corresponding colour was at its minimum of 10%.
It looks to me like each 0 represents 1/1000th of the wheel, since 10+10+10+10+15 = 55% of the wheel is already accounted for by the fixed size black and the 4 10% minimums leaving 45% represented by the 450 0's you shuffle. I'd like to see this explicitly stated in your 'how it works' section.
