Thank you for your swift reply. Especially thank you for being straight forward discussing with me the commission fees.
Regarding the final price from the proposal, it was communicated with buyer on the range of 5-10% additional on top of the mentioned price in the proposal. The idea and concept of the tower and construction method was clearly communicated with the buyer.
Hence, if possible I would like to request from you at 7% of commission instead of offered 5%.
This project is somehow has a very high potential. I can ensure that the buyer will add on any optional which may critical for the project.
Please feel free to discuss if you have any concerns.
Highly hope this request is agreeable with you.
