I am building up my portfolio and thus the low bid price. The working culture in my country is to deliver the project to the user expectation and satisfaction. (within reasonable limits) I had just finished an excel macro project that allows the user to key in information and then generate html in outlook. If you will like to have a look, will be pleased to provide you upon request.
For that project, I charged 4 mandays but there is no mention of the requirement to have concurrent access in sharepoint (although at one time, only 1 person can have write access). To resolve it and have the UAT sign off, I spent in total more than 4 mandays (bulk of the time is spent downloading softwares and installation - virtual machine, windows server, sharepoint)
