building a customized spreadsheet

I am a retiree who's tax domicile is Israel who has a small portfolio of personal investments , and I am also the director of a Canadian based investment company investing on behalf of three family members.
Every month I currently download and annotate by hand the data from 9 different bank accounts, and using my own excel spread sheet I analyse the credits and debits from these statements. There are less than 50 relevant enteries every month.
Knowing that the bank statements can be downloaded directly in excel I am interested in streamlining my monthly recording.
I see three goals to my project:
1. to create a spreadsheet compatable with the banks' reporting features (excel or other) with drop-down choice boxes that allows me an easy way to annotate the enteries on the bank statements as there are a limited number of categories for discriptors for the "credit" and "debit" entries.
2. having entered the monthly data, according to the predetermined descriptors, I would like to be able to access easily the income from the various investments, the cummulative transfer of capital to and from the 3 partners and the company (individual investment and payouts) and between the partners (for example loans and their repayment) .
3. the final goal is to have the program integrate the data so as to be able to calculate the financial status of the company and of my personal equity at a single click at any given date.
I feel that it would be sufficienty for the program to generate tables for the above questions, but I would also be interested in learning about the extra cost entailed for converting these tables into more attractive graphic presentations for distribution to the 3 partners in the company.
My goal is receive a system that will run from month to month with little or no further input from the programmer; however, I imagine that some ongoing help miggt be needed from time to time to tweak the program or to modify, expand or improve it.
