- Additionally I need Google Ads tracking sorted for this so I can track the purchases via google ads

The budget stated is the final amount, start your proposal with i understand or it will be ignored. Additionally I need references of similar agency sites so I can see your design skills. If there are no references/examples of work done the proposal will be ignored.
