Request PHP Programmer

I am writing to make a special request. I am 69 years of age with an ecommerce website that had Google Merchant Checkout for my at home business of Counseling Psychology. Google, Inc. retired that service, so now I have to use Google Wallet. However, there is some PHP programming that I am unable to perform as I am not a programmer. I have tried to figure it out on my own by reading from my local public library PHP books, but without success. Would you by chance have anyone who could provide 1 hour of free time with programming PHP. I was a student at a university and found a college student who assisted me for free as a courtesy to a senior citizen, but he is no longer available. I do have a good portion of the client and server side code operable for a template, but just need some refining so that I can use one template for all of my ecommerce HR testing. It would not take very much time. Do you know anyone who can assist me. Because of my age, I live on meager fixed income. So, I need free PHP programmer to assist me so that I can get my web site operable for Google Wallet Buy Now transactions with PHP. Theresa Bradley,Psy.D./LPC
