SSIS Design Question - New To SSIS, Please Comment! :)

Hello everyone!!

I am completely new to SSIS and have been given a large project (of course with a tight deadline) that has the absolute requirement of using SSIS. I am/was very, very good with DTS and could easily accomplish what I need to do with an ActiveX script task in DTS in no time, but as this is new development, we are not to use ActiveX script tasks within SSIS since it will not be supported in the next SQL Server release. I'm thinking script task, but please give some comments on how you would accomplish the following in SSIS (please remember I'm new to SSIS, so don't assume I know anything. )

I must accomplish this: in a nutshell, I need to create separate tab delimited text files of customer informaion. One for each region. Each region consists of X amount of states and we have X amount of regions. (Pseudo code followed by standard explanation)

Select a max value from region lookup table in SQL (this is the # of regions)

for N=1 to MyMaxValue

select states from region lookup table where region code = N (the current region we are on)
'this returns a list of states in a region, need these in array or recordset object or something
Open an output file which will be a tab delimited text file we will write results below in loop to (in DTS I would programatically kick off a transformation task in the package)
'loop thru states returned, so if in a rs object...
do while not rs.eof

execute customer stored procedure, passing as a variable the current state we are on
'this will return all customers within a state, this whole result set (approx 1 million) needs to go to the tab delimited file
'I have to execute this stored procedure for each state & then write results to the SAME file, until we are onto a different region

rs.movenext
close file
loop
next

OK, so basically, as you can see, Its sort of simple in a way what I need to do, i just have no idea how to go about doing this in SSIS. I can not hard code any state or region values. I MUST read them in from the lookup tables as region codes are constanatly changing and we are constantly adding in new states and new regions, so with above coding idea, it would always dynamically pick up any new states, new regions or changes.

So in a nutshell, I need to create separate tab delimited text files of customer informaion. One for each region. Each region consists of X amount of states and there are X amount of regions. Pretty strait forward, huh? The requirements are strait forward, but SSIS is throwing me for a loop... it does not seem flexible enough to be as dynamic as I need it to be to do this. I'm sure it is, just my understanding of it is very basic so far.

Please provide your suggestions! I think a lot of newbies would benefit from some SSIS design info... how to do common things in SSIS, but beyond just retrieving a recordset and writing it to a file... what do you do when you need to add just a few layers of decision processing, and retriving recordsets and writing files based on that decision processing?????

THANK YOU!!!!!!
