Time will start either at the retailer when picking up supplies or arriving to your home to start work. Depending on which comes first. I take payment in check or cash in person. I do not have a credit card terminal. I have a PayPal business account and can take visa, mastercard, and any other payment accepted by PayPal via my Pay Bill link. There is a 4% charge added to cover what PayPal takes for those payments.
Materials
All materials required will be paid by you, the customer. I will create a materials list for you and go to the supplier of your choice, Home Depot, Lowes, Dunn Lumber, etc. to pick up supplies. Upon check out the salesclerk will complete a phone sales with you to purchase the supplies over the phone. If I am at Home Depot you can use your Home Depot card or at Lowe's you can use your Lowe's credit card. All retailers will take visa and mastercard for phone sales. You will receive a receipt via email from most of them and I will also give you the printed copy.
Or you may shop online to purchase the supplies to have them either shipped to your home or for me to pick up at the store, be sure they tag your purchase with my name for picking up.
