Hello Tricia, unfortunate first thought is that contracts available on the web for free are typically not sufficient to protect yourself and your partners from any future challenges problems or litigations.

1-The contract between you and your client depending on the product or service that your offering may be drawn up by yourself without too much challenges if it is not a complicated contract i.e. I agree to sell you X for Y price, and a description of your delivery time, payment terms, and the purchaser's responsibility.

2-A contract with the factory might be different especially if it is with your Chinese factories. Definitely this contract must be written by a lawyer that knows about international law. The Chinese are a very difficult group of people to deal with and you must protect everything and I state everything in this contract.

The more I think about your question more would really recommend you to meet with a lawyer. I understand that there are expenses to meeting with lawyers but unfortunately these expenses are necessary if you're dealing with the Chinese government, factories, for people..
