Another good option for contracts and proposals is HelloBonsai. It’s an online service where you can start for free. It has proposals, contracts, and almost everything you need to get started.
So, if you want to see an example contract just go to https://app.hellobonsai.com/sample-contract .
And if your freelance practice grows you might want to pay for this. $19 or $29 per month is a small price to pay to have electronic billing, time tracking, and help with proposals and contracts.
