Yes. We can organise the taking of money at an event if fundraising is required.
Predicting if and the amount of profit is difficult because it depends on many factors, which are often unknown prior to the event. Low numbers willing to take part is the principle problem.
If guests have paid a high-ticket price, done the raffle, the charity auction and paid inflated drink prices etc the mood to get their wallet out may have passed. In which case the slot track will remain unused and return a loss. In these cases it is better to include the slot-racing costs in the ticket price. Take the long term view that if guests enjoy an event overall they are much more likely to come back next year.
As general rule groups of 300 people or more, given the time and opportunity to take part are likely to return a profit.
