To be a dime a dozen means to be very common.

Example:
- Pizza places are a dime a dozen around here, just pick one and order some lunch.

Don’t have two pennies to rub together means not to have money at all.
A company or a person that does not have two pennies to rub together is completely broke.

Money is no object means money is not a problem and could be spent freely.

Example:

• You should see the new office building, obviously money was no object.
• Let’s forget about the budget for a moment, How would we plan this research project if money were no object.

To cash in on someone’s fame means to profit from someone’ fame like supermodel or celebrity.

Cashing on something means to take advantage of something in order to make money.

Example:

• Do you think TV networks will try to cash in on this scandal?
• It is awful that some shops are trying to cash in on the recent storm by doubling the price of a bottle of water.

To give someone a run for once money means to give a competitor an equal challenge.

Example:

• I thought bill might easily get the promotion, but Jean is certainly giving him a run for his money.
• the new department store is giving the small shops a run for their money.
