I've been planning this thing for years! It requires the addition of text descriptions and images from registered customers that would be displayed on a page on a long-term basis. Users would be able to contact/buy the services offered and pay direct.
First I decided to go with a custom application PHP and mySQL .. the guy kept my 50% and "got too busy" to continue. Second programmer didn't want a deposit, but never delivered.
Another way might be to use Joomla and a directory plugin and specific secondary application to do the business end .. but the secondary application has some quirks.
And then, PayPal integration.
I'm worried about my server getting bogged, about getting hacked, etc, etc and wonder if the old fashioned way may not be better.
I'm thinking about an emailed form (from my customer) that I can copy and paste to a HTML page (or inserted by me into a database) with all the "pay me the money" links to the customer's choice of payment plans.
Am I working my way toward a disaster?
