I'm biased towards Billy Goat, but I'll give you my 2 cents. If you're really trying to avoid retail watch Craigslist (be careful though) or check with rental companies to see what they offer. They normally have wheeled blowers and vacuums. Rarely do they have Debris Loaders but it does happen. Another option is subbing it out to another landscaper you trust.
