OSCommerce Multi Store Admin FIXES

Hi, I need an Oscommerce expert who is looking for a long-term relationship to work on several projects. I've had bad experiences with a lot of programmers on GAF (disappearing after payment for support, not commenting the code, not documenting changes, bad coding, doing half of the work etc. etc.) so I'm looking for someone who is reliable, works with accuracy, is fast and has a good track record. I have a highly OSCommerce installation with the Multi Store mod, but it is still buggy. The orders and customers are not showing up as they should in the admin. It's not possible to trace back customers to the shop they signed up in. When placing orders in the "Default" shop, they are processed (mail is sent and stored in the database) but they do not show up in the admin area. I need someone who has experience with this mod to look at these errors and fix the ones I point out and the ones that come up. It shouldn't be a lot of work for someone with the skills and experience I'm looking for, and I consider this to be a small project. I would like this to be done within 24 hours, so please respond and provide me with some reference work. As soon as this project has been finalized in an orderly fashion I have many other projects I'm willing to work on with the selected service provider. Thank you and looking forward to a professional long-term relationship.
