Realistic US Capitol build for political sim

Hi! I'm trying to make a political simulator about Congress, where people pass bills that advance the nation's goals (or theirs), pursue alliances, burn bridges and do anything to cement political power and sway others. If you've ever played the Roblox game Oath of Office (formerly Executive Orders), it's like that but centred around Congress and bill-passing and large-scale co-operation.

I already have a map of the interior of the Capitol that contains much of the second floor and parts of the third - this is nearly everything that is required in game, but I need a modeler to fix open gaps as well as complete extra rooms (namely, the areas highlighted in yellow in the image provided) so that they fall in line with the Capitol blueprint. Many of these extra rooms are offices, and there are existing assets in the map that can be used.

It should hopefully go without saying that builds should be reasonably optimised and fit realism standards included in the map and assets involved in the incomplete map aforementioned.

The deadline for completion would likely be 2 weeks from first payment, but note that this is not a strict deadline. I do, however, expect clear communication throughout the process so I know what's going on and can hopefully correct anything if things do not follow the intended vision.

You will be working solo, but I'll do my best to provide references and anything else you'll need. If there are any further questions, please reach out!

Please attach portfolio for consideration.
