Small database / online portal

We want to create a small online portal where our staff can input data about each call or chat, and then we can easily view the statistics on the calls and sales. Attached is a pdf document with screen shots of how the database will look and function. We have 2 different company names (2 brands) so we want to keep the statistics separate for each brand, and also be able to filter the statistics by date and country. Statistics will default to showing the stats for the current calendar month, with a quick button for the previous calander month. There are other quick view buttons too, again, you can refer to the attached PDF. We have no set deadline, but do want this as soon as possible, so please give an accurate time frame for completion as well as your price. It is important you have a portfolio of previous jobs, or references, so we don't waste time with a beginner. We have had some big portals made, and being made, but our current programmers are too busy for more jobs, so this is a chance to meet and find a new quality programmer to have you on our list. I am not sure of the price for this job, so I am just selecting the default of 250-750. Put a price of what you think is fair, and we will evaluate according to your experience, skills and previous jobs. Thank you
