W9 Form

My LLC is set up as a sole prop but I have an EIN... I am going to be bird dogging for an investor that is paying me to find vacant houses take pics of them and submit them to him... He pays me per house no matter if he buys it or not...

Well he wants to pay me as a sub contractor and I need to fill out a W9 form. I want to run it through my business... Question is do I need to put my EIN number or SSN? I would rather file a seperate tax return at the end of the year for my business...

I am also on unemployment right now and I was thinking if I can run it through my business I could keep my unemployment coming in until I know this job is making me money and then the business could start paying me.

I don't know if this is a good idea or even legal so please any advice is appreciated!

Thanks
