Consulting: OpenCart VS CNET

I want to plan a business before implementing one. Your job will simply be to discuss my business plan with me via skype. Available Monday-Thursday 6:00-11:00 EST. All day Saturday, Sunday. I am looking for a store site solution, and have been looking at OpenCart, but would be open to other ideas as well. Anyone familiar with the functionality of CNET's Channel online is beneficial. I am looking at OpenCart. I need to know it's flaws. I want to integrate with Ingram Micro, Tech Data, DandH, Synnex, and if you know of other such distributors, I would like to know that as well. I know very little about open cart, which is why this is the planning phase. CNET is expensive, charged by the login monthly, and has limited functionality, and I personally think its full of bugs. I want control and customization. I need reporting. Sales by manufacturer, sales by "Contract" (will be a manually added field). I need to know how integration works, and be able to add my own cost and pricing for items sourced elsewhere. I need to be able to produce professional looking quotes, preferably in PDF, and email them to the customers, preferably directly from inside the website. The goal is two fold. An internal store for inside sales reps, and an external store for customers shopping. Email marketing - "eblast" functionality will probably be necessary as well. I will think of more. So there it is. Easy money. Consult me on an OpenCart project before it even starts.
