He is also wanting to know what the pitch for the trim would be and Im not sure how to figure that out.

If you are not residing we have a replaced a would window with a vinyl window with vinyl trim and frosting (crank out). 

I am looking to hire for  mobile home repairs and landscaping/tree trimming/yard mowing services.

Especially if yourgoing to replace all the sheet rock, trim. base, and doors. 

Around here, a typical lawn costs about $40 for a mow, trim, blow.

Completely rebuilt it from the studs out, installed new wiring, new plumbing, HVAC, drywall, paint, trim and restored the original windows and hardwood floors.

Some homes cost $8,000 to $10,000 and one home in Idaho cost me $18,000 because the tenant destroyed every plumbing fixture, kitchen cabinets, stove, refrigerator, granite counter tops and it took several days to trim trees, etc.So, we lose 1 month of unpaid rent $2300 + $8,000 to put the house back together + 30 days to complete the repairs + 30 days to re-rent the house $4600 for loss rent + your tenant owe the utility companies $800 = $15,700 and this is if you are lucky and can do the work yourself.

Make a list on a yellow pad of every picky thing that needs completion: drywall, type of texture, electrical outlets, molding, all the interior trim, I assume you have pre-fab cabinets sitting in a garage if not - you need to, doorways and door hanging, all the walkways and outside hardscape are done?

Trim the fat and you’ll be more lean.

As to getting accurate labor costs, if you can form a relationship with a contractor, you can certainly pay him for his time to do one sample bid for labor on all the items you should need (window install labor, trims per LF cost, hang/install interior/exterior door, demo a bathroom, demo a kitchen, demo flooring, tile install floors and walls per SF, etc.)
