If you have trouble with the technical side of things, I recommend asking at sites such as elance.com or scriptlance.com – the folk there, all freelancers, bid for jobs that you specify. Another useful place is the forums at forums.digitalpoint.com
As for starting out, personally I’d say start at the bottom I don’t know your level of experience, but ebay is always a good learning ground, followed by your own site using resellable software or affiliate stuff, followed by your own product.
If it’s an all in one business plan you’d like, something step by step, I’ve always liked Marlon Sanders products (google him). Everything marketing tends to follow a theme, copycatting each other, but his stuff stands out. Other avenues to explore are blogging, adsense sites (bearing in mind the stuff mentioned at this post), and pay per click marketing — but be very careful what you spend there.
Most marketing products are honest in a way, just never believe the income claims. They should have small print to that effect, so take notice of it.
