Does "help" mean you are doing most of the work and need technical help or advice?
Does "help" mean you want someone else to do most of the work? If this is the case you are likely to find that the quality and amount of work done by others is related to their motivation - if it's money then expect less for paying less.
With the above in mind - your situation might present an opportunity for a professor/teacher to give students some real world experience in exchange for their labor - whether in design or construction. You might contact local schools - high schools or universities, depending on what you are looking for and where you live.
