Letters and post cards work well if they are prepared well.

Best advice with contractors is always warranty, insurance, pay with card(if theres a 3% fee so what) and no large deposits.

and its going to be a debit from seller right ? 

I then disputed the charge with my credit card company and the SAME DAY I receive a notification that the package was being sent!

Because what's going to happen is this is a scammer using a fake or stolen credit card, and you won't get paid. 

@Steven Catudal You are free to deduct and will probably get away with it.Do keep in mind if the tenant sues you hold very bad cards for court.

Waiting to see the process of cancellation and hoping it’ll be as smooth as when they eagerly swiped my card 😀.

They also have a "reserve" fee in which they collect 10% of every credit card transaction and hold it for 90 days before releasing it back. 

Ask if they take debit cards and credit cards or must you write a check, The way I am comfortable with paying is payment for the job x amount, payment for the decorations according to a gross budget for everything, as they are purchased vs giving a pool of money to draw from.

Would love to hear about raising debt, possibly ... credit line investing / credit cards for downpayments...?
