Event Table sitting with access DB

Hi, I need to Put together a database of names with sitting allocations that would be used for Events and Functions for Staff to Locate guest sitting allocations Quickly as there could be 500 or 700 guests wanting to find where their sitting. For this coming event there will be 2 Laptops used to handle the quantity of guests and so i thought Access DB would be good to use as the Original DB can be copied to the 2nd computer to be used and that the computer does not need a Any other software except access db to run the database. But if you have better ideas please let me know. Also I need this done very very soon!! In Access You can create from a pre existing template (contacts List) and i quite liked the already created fields and tables like address, contact number and that you can add persons profile pic so i would like you to perhaps use this but change it to what i need. So I would also like to have a sitting Plan or Image to show if i choose so that i can visually also see where the table is located. ( this will be all different images i believe) The database should use relational system i guess. Also They should be able to Search By Name and Or By Last Name and to use like AJAX where it displays the last names or first names after entering just the first letter and narrowing it down. I like to make this as good as it can be so it can be used for other events. Can this also have an import feature from Excel. I have attached the db that i tried to do myself using the template (contacts)
