The point about the sourcing is well taken. Might be better if I just say I don’t do it. It really is something I am very hesitant about normally, given I don’t want to risk relationships on either side of the client-supplier line with me stuck in the middle. I’ve seen it go bad both ways. The client (brand) doesn’t go to production, or is a lot of hassle for the fty, or the fty doesn’t pull through and cancels production leaving the brand in trouble. I always also figure there isn’t much in it for me to take the risk. I’m not an agent taking a % of FOB, so while I can offer sourcing for a fee, long term there isn’t enough benefit to reward.
I think I’m going to take all the sourcing stuff off my site too - yes I do offer it, at my discretion, but 99% of the enquiries, prototyping is all they’re interested in. I think my clients tend to be different to yours, with different needs. My two main ones, I don’t hestitate to introduce them to any resource, because they place orders. My two current business start ups have placed good orders too. But I think it’s best to not advertise it. You can still offer it, in private at your discretion.
Also good point Shoenista about the business plan. It is indeed important, though often I do work with clients who don’t have one, but have a sound concept that I can help translate into a business plan and opportunity. That’s really part of the my services given I work from branding +, not just design
.
My point, is the business start ups I’ve worked with successfully didn’t have business plans either, but they were very clear about who they were, what they wanted and where they were going with it, they had the plan in their heads.
As opposed to, ‘I love Jimmy Choo/Nike/insert brand here’ I want to do the same but different. Which isn’t a basis for a plan.
Hopefully the FAQ helps weed out the ones with no chance.
If they read it 
Do you think it is too much info to have on the website, or should only be provided by request?
What I did on my site was ‘Notes for New Clients’ which is an edited version of what I would email out. So you could put a shortened version up for public view.
Do watch out though, people can be very fond of copying your copy. So for that reason again, I wouldn’t put the whole thing up for public view.
