ALOT more then an 8 hour job, if you have any idea how complex it is, you would not be saying this. Rewriting oscommerce ruins its functionality and defeats the purpose of using it to begin with. If you don't like the way osc works, then I sugesst you use something else.
I am posting on this bid to make everyone aware that this project is alot of work and will cost thousands to do. I don't want to see anyone get burned by this uninformed project post. Nor do I want anyone to misunderstand this guy, he is just misinformed and doesn't know osc very well. I know because I am a osc pro and have been for many years.
Good luck everyone!
