The way to find an advisor:
Why not try working for free with someone whom you consider a role model in the business world?
You can start with small or large companies within two or three months. If you like it then ask them to be your advisor, then they should agree.
In case of refusing, you will at least have learned enough from them in and then you can try with another one. If you preferred to work for a year without getting paid, then after this period, you will have sufficient skills to start on your own.
