I can most definitely feel that pain too - I have huges lists of things that need done and no money to do them nor help to get them done most of the time as I am on my own and have virtually no income that isn't spoken for months in advance for hay or such.
In my case the answer is either very slowly and in terms of hot days starting early - I managed to get 2 of the fields sprayed for ragwort this year at the right time but he never came back to do the other 2 and after last year, when he was so late returning that the last two got sprayed and still needed large plants pulling barrow by barrow, this year I have just got on with the other 2 myself, working 8-9 every morning because it has been too hot for me to do much heavy work. They're done now and I've worked round 1.5 of the sprayed ones' edges pulling the plants the sprayer didn't get along the fenceline.
On another occasion I had to stop getting help with a chainsaw to take down trees because I couldn't pay the guy any more. So this year my neighbour came with his chainsaw and took 2/3 of the wood in payment for his logburner. It was 50/50 in principle but in practice I can't manage the big logs and he can, so I got the top half and the bigger stuff he took to split and saw himself. I had to let go the idea of it being mine and settle for what I could get as better than the tree falling on my house (the root was damaged by flooding last winter so it needed down!).
I've had a couple come to stay and help in return for a free holiday base, they were away out most days but helped get a couple of major 2 person jobs sorted and that again was worth it to me. I tried a lodger which worked for the 2 months she paid nothing and felt she owed me time, though she wasn't that much use in heavy work she did spell me with feeding a sick foal through the night and that was worth it in sleep. Then she asked to stay on and pay rent, paid me only the 2/3 of it she got in benefit and never a penny of her own, then went to get a part time job to pay the rest and I never saw her let alone got help as she was always taking extra shifts, money for which she used to pay for courses and holidays and books but it all got a bit much for her so she moved out and I don't think I'd do that again! I also lost my council tax single rate while she was here and of course got nothing towards that or household bills, so just got a load of paperwork and ended up out of pocket!
Now I just do what I can when I can manage, get a good day and I motor on til I can't do any more in case I don't get another good day for a while! Then floored for a couple of days and behind again. I think I have just let go of the big ideas and focused on the smaller stuff and the necessary stuff. The barn roof came down in snow 2 maybe 3 winters back now, the rubble for a retaining wall at the barn edge has been on the roadside from a collapsed garden wall for 18 months because I can't see the point in moving it twice, the place looks a mess and could look amazing with money thrown at it, but I don't have money to throw so I live as it is. And I used to help folk out all the time when I was young and fit and keen, but now I can't offer much at all so I don't ask. I do offer what I can and hope at some point to build up enough global credit that I could get help in an emergency if I had a stay in hospital or on crutches or something, but I dont' want to waste any goodwill on anything less and I hate asking anyone for anything anyway.
