This sounds like a very complex case. I would highly recommend you consult an attorney and discuss the specific details of the deal. I do not think you will have a lot of luck getting any kind of response (detailed or not) on this site.

Any sale of a business is complicated and full of risk. I can't tell you the number of cases that come my way where a business owner has tried to sell a business without any legal help and then paid 10-100 times more in legal fees later.

That said, I handle these types of matters and would be willing to discuss it further. Feel free to contact me directly.

What do you mean by "sell my business via the internet"? This may be a satisfactory way to locate a prospective buyer or buyers. However, you surely don't want to conclude a deal with buyers you haven't met and gotten to know!

The first and foremost problem with small-business sales is for the seller to get paid. If the terms are not 100% cash on the barrelhead, the seller needs collateral and deeds of trust or security agreements sufficient to perfect a secutiry interest in property worth well over what is owned.

Once the problem of getting paid is handled effectively, the sale negotiations should cover deal terms such as indemnity of the seller from post-closing liabilities of ANY kind resulting from the buyer's operation of the business.

For both of these concerns, you need an attorney with sale-of-business experience. There is no substitute. Nope, NONE.

All of the normal issues and problems of selling a business, complicated by privacy and confidentiality issues can be dealt with by experienced counsel. You'll need a properly drafted sales agreement with all those issues negotiated among the parties, and covered in the agreement. Feel free to contact me for the legal help you'll need.
