If anyone has done this type of project before and has a detailed/itemized breakdown of project cost (invoice), I would truly appreciate if you can provide me with a copy and any guidance.thanks!

Have an itemized   Otherwise your bill will go out of control and you won’t know why.

In The Tampa Bay Area local investor in the items inside the home/business but looking to get with the right people to build a team.

Hopefully the deposit covers Jan rent, make sure you give them an itemized list of the money owed to you for any damages or unpaid rent. 

If there are items of value left behind, or even personal items of sentimental value, I will follow the abandonment rules to a "T" to avoid any legal issues.

Manage their properties Provide welcome gifts/ goodie bags for their guests before check in Hauling extra supplies/ misc items to return to stores or other properties--Any other ideas that I can pitch to make myself more marketable?

I think the removal of toilet seat and items bolted to the walls show malicious intent as well.

What were the biggest line items?

Although the list may seem intensive, I look at it like this: The total cost of all these items can be much lower than the cost to repair a hidden surprise after purchasing a property to flip. 

Per him, Judge will see how unreasonable he has been in his itemized list and not award a windfall anyway.
