For the last 4 years I have been working (as a contractor) for a New York startup that recently got a large investment. With the investment, they have started to be more grown up and for my contract renewal I received a contract with new wording.

There is one section "Ownership" with three paragraphs, and all of them scares me.

To me it reads as they will own anything I produce during the term of the contract that is related to the line of business they are in (which can be a very broad term depending how you interpret it; and I read this as they will own stuff I do in my spare time as well).

Anything (code, ideas etc) I create in my spare time I have to disclose to them so they are aware of it.

And the final clause is that they have the right that for all eternity sign any papers in my name to protect their intellectual property rights.

I am now looking for advice on this.

Ideally I want to find some standard paragraphs that I ask them put in instead. It should give them all the ownership of the code I produce for them, but anything that is not produced for them is none of their concern. (With exception if it would be something that could compete with them).

Anyone can give pointers to where to find such standard clauses?

Does anyone have recommendations for someone that does review of contracts (this is a New York contract)

Anyone have an idea what such a review of these paragraphs (or a whole contract) would cost? (just a ball park figure would be great, since I have no idea if it would cost 50 USD or 50000 USD)

The rest of the contract looks fine, it's just these paragraphs about ownership that are scary.
