I suggest for anyone doing consulting or building an app that they build into the price a monthly maintenance fee as a residual I do this on many non-coding consulting gigs - and I know other folk do too. More because walking in then walking away means that clients often don't get the full benefit (since they fall back into old habits or have questions) so they need some ongoing support. Unless you get successful improvements you don't get the referrals - so it's not just about getting extra money on an ongoing basis ;-) So, for example, an engagement might look like * 5 days onsite * four weeks of being available one day a week remotely/onsite during set hours * N weeks of some number of remote hours / onsite visits depending on client/location.
