Dear sir,
I understand from your proposal that you need an expert MS excel. I can do the job for you in a more efficient manner and in a relatively shorter time span as i am experienced in working with excel spreadsheet. Actually, i made excel workbooks before which had all different data types as well as interconnected sheets. I can make the workbook for you and then enter the data you provide.
I can email you my sample excel workbook if you want me to.
Or i can do a sample for you with your provided data in just 1 or 2 days if you want, before you finally decide to provide me the job.
Please feel free to contact me, i am hopeful that you will be benefited working with me.
