Hello,
I am the true professional you are looking for. I have over 15 years of experience in various programming languages, development techniques and technologies. Please see my certifications and customer reviews for my credentials.
Your project seems pretty straight forward but I must ask (better safe than sorry) is there any specific functionality besides a simple store front and custom ordering system that you will be needing?
What payment gateway would you like to use with this project? PayPal, ClickBank, Merchant Account system?
Do you have a layout or template you would like to use? Would you like to mimic an existing site or do you also need custom design work?
Do you have a hosting server / environment you want to use or will you also be needing hosting for this project?
If you can provide this additional information and answer these questions I can offer you some better suggestions and a possible solution.
