Hello all, I just recently started my own landscaping business. I'm bidding on a project for a house that is getting ready to be sold in the next 6 months. They have a $10,000 budget for landscaping and want to make some big changes on their property before it is sold. The first thing they want to do is replace the current turf with brand new sod which is approximately 1000 sqft or so. They want to replace the bushes in the front with new ones. I have experience in all of this and well capable of doing this. I also have the necessary help to get the job done. My concerns and questions come from their request of building a 3 or 4 feet retaining rock wall in the back yard. I have never done this before. They also want to put up a fence to close off the back which is about 20 feet long. I also have never done this before. If I bid, and win this job. What should I do? Subcontract it out? I would really like to learn how to do these things myself so. How do I do that though? I have much prior experience with landscaping in renovations, and installations. But rock walls and fences are my weak points. Any advice, and suggestions would be very helpful and welcome. Thank you!
