Here's the deal. I was asked to give a maintenance estimate on a decent sized nursing home in my area today. Assuming I get the job for next season, they also want to completely redo all of the flower beds. The budget for improvements is $15,000. I don't plan on creating many, if any, new beds, I was more thinking I'd replace the existing tired/overgrown shrubs and flowers with new ones. Now to be honest, this scope of design is beyond me, I plan to sub it to a landscape designer I know to do the plant selection, layout etc., and I will do the removal/install work. So my question is, is there a formula you guys use to figure out how much money to spend on plant materials and how much money to dedicate toward labor? Like should I tell the designer he has for example $5000 to play with including his fee? I realize of course there'sa lot of variables, and no two jobs are the same, but is there a way to figure roughly what percentage of the budget should be dedicated to which aspect of the job. I appreciate any advice anyone can give.
