You can definitely submit an offer without a buyer's agent (we just did this successfully with no issues) - the listing agent should have you sign paperwork that they are not representing you, but they are just facilitating the transaction.
Can I write my own contract? Yes, you can write your own contract. However, including all necessary elements is crucial to make it legally binding.
