Bi-Directional Sync API Vtiger & Magento

Hi. I need to get bids for a small API to be built into my vtiger/Magento accounts See the below links for api information VTIGER: [login to view URL] MAGENTO: [login to view URL] JOB DETAILS: - Must Bi-Directionally Sync - Conflicts should resolved with the newest edited record. - Must have a "form" in vtiger where you can connect magento to it. This will allow us to update credentials in the future if needed without hardcoding. - Need to have a "log" section in vtiger for reviewing of everything. - Should also include in settings somewhere a option on how many minutes to update on a schedule type deal. Every minute, 5 minutes, 10 minutes etc. MAPPINGS: ************************* Vtiger to Magento ************************* Customer to Organization (along with all related information ship to, billing, etc) Product to Product (Should include pricing, a cost field, sku, images, category, QT, Description to Long Description) Sales order to Sales Order Invoice to Invoice Categories to categories All these API's are pratically built already and tested. You just have to fill in the information. There will be a few things that may get removed or changed along the way. , , but its hard to say what or how until that time comes. Thank You
