My client has set aside a pretty big budget to learn this new tool, so they themselves can be classed as experts in multi-channel marketing. I don't really know the inns and outs of it all, but at the minute I am assuming my role as a developer is the know how to integrate this tool into e-mail newsletters and websites.
My client is very important to me, and is by far my biggest client, however, I'm not sure how much new work I'll get a result of this new tool they'll be using, as they'll only be using it with certain clients, which at the moment, are not clients I really do much work on projects for.
My vision for my company is to become experts in internet marketing, so I can see the appeal of doing the training, but because my involvement in the new tool is only part of it, I would still require someone with the necessary skills to use this with other clients. There are different parts to the training, some for the marketing company, and then training for the developer.
To be honest, it's only going to be around a £1000 investment from me, but if it only results in extra 1-2 hours of work per month, it's not really worth it.
