I have noticed your approach really should vary from business to business. I'm no expert though.

For larger corporations, don't waste time calling and asking people. Find out if they have a grant program, and apply for that. If a larger corporation doesn't have a grant program, I guess call until you find the person who can help you with that. Each time you talk to someone there that isn't the right one, try to get as much advice and info as you can from them. They can provide a lot of tips on what to say to the correct person if you just ask them to. It may sound weird, but it's worked for me.

Have you considered trying service clubs? Kiwanas, Rotary, etc... usually have grants you can apply for, and if not a grant, you can just ask them to support your team.

In recent times I've been contacting machine shops and they seem to require an entirely different approach. They don't like having their time wasted, so call, give a very brief line and ask them exactly what you want (Don't say, can you assist with manufacturing, say can you make parts for us). I'd assume small businesses would require a similar approach as they are usually busy as well.
