Where to ask “what it’s worth” questions

For me it's more when then where. For someone who's been on the forum and needs a little help that's no problem. But for someone basically brand-new or has asked only or talk two or three times...
You know kind of like you want me to do this favor but you haven't even offered me a cup of coffee?
You're probably okay right here just as long as people don't start making offers... As in right here on the thread and knot personal messaging you about it.. or they'll just shove this in a for sale part...
How can I agree and thank you at the same time.
