I know you must be disappointed as there is nothing wrong with wanting to promote any legitimate business activity that you might be involved in but that wouldn't be acceptable on Hubpages.
It's a site for self-publishing rather than self-promotion in that sense.
However, with the correct approach and plenty of determination to sow now and reap later, I understand that a great deal can legitimately be achieved through social networking sites such as Facebook, Twitter, Stumbleupon and so on.
You might also try eBlogger or a free Wordpress platform to set up a simple content site with your links on. You could then use these means to direct traffic to that.
You are setting out on a hard, hard road to earn an income, taking the affiliate route. It can and does work for some but be prepared for it to take a lot of time and even more hard work up a very steep learning curve.
Thank you for asking this before doing it. So many don't and then wonder why their work is rejected here. There is a lot to learn but I assure you it is worth the effort as the rewards can be considerable.
