So can someone tell me about how long does it take to make an order from for eshopping that automatically emails the customer the invoice and/or payment?
Any takers who can answer this one for me? I would really like this. I believe this individual thinks that it should only take a few days at the most. Are they right?
How long it will take to develop the script itself depends on what exactly are the requirements. If it really is only an order form that sends an email (and presumably records the order in a database), it should not take more than two working days even with your limited experience, assuming you can adapt your company's existing website design.
The problem is that you need to acquire that limited experience to begin with. Let's see:
1. Your programming skills are rusty.
2. You do not know the programming language and related technologies (in particular, SQL and database design).
3. You are working alone, and thus do not have a mentor.
How fast you learn depends on how well you can adapt what you remember of programming to the technology you are using now. It may take a day or two, but it could also take a week or two.
Of course, an order form probably does not exist in isolation, and if you have to do things like a catalogue and shopping cart, such a project may easily be on the scale of a few weeks, unless you configure an existing script.
