Retouching of approximately 20 interior photographs

Due to time constraints, I need somebody to work up some hotel interior photography. App. 80%of the shots have had multiple exposures taken (2 or 3), as i need to ensure that e.g. the inside exposure is balanced with the outside exposure and you can see the external views via layer masks. Also, any heavily under or over exposed areas need to be reduced by layer masks. This is a specific composite job only and for somebody with experience of this, it will be quick to get good results. Each image must remain looking natural (this is not about HDR) but captivating - vibrance and sharpening will need adjustment for example. Attached is one example of the shots taken. Images will be sent via wetransfer this evening and need to be returned within a week. Please send an example of this type of work or a low res edit of the attached images. Please also provide your price for the job based on 20 but per image cost in case there are more to do. Thank you
