I guess opening a shop just through the inline credit system is not a good idea neither for forum.

and why is that? I don't see anything wrong with it. It's requester's choice to whether buy one or not.

OP: I'd like to see a portfolio or something as I'm looking to get business logo done.

If you thinks that is a good idea then it maybe a good idea, well why don't the OP share his previous designs/portfolio so you can find out his professional skills in GFX designing.
