shop drawings for precast concrete products and reinforcing (rebar)

We are a small precast concrete company. I need someone to update our drawings. In some cases, we have existing drawings, that need to be updated. In other cases, we have no drawings - for these products, we would send you sketches or photos with dimensions and reinforcing details. Products include: pipe, garbage cans, picnic tables window sills, parking curbs, planter bowls, stair treads and more. I will provide a fairly detailed initial drawing that I will ask you to redo in your own style - likely an upgrade on mine. The first drawings will be simple and we will move on to more complex drawings from there. I will want the drawings AutoCAD - or something similar as long as I can get the software without spending Thousands of dollars. (we currently do not have autoCAD and have been using CAD Standard as our drawings are quite simple. We will also want PDFs of each drawing. We will want our logo, address etc on each drawing. As Freelancer does not like us to have any contact outside of Freelancer, this will have to be addressed - if we are supplied the drawings and can get the software, I can turn them into PDFs. We would also like 3D drawings of some of these - this would be an added bonus, but not a requirement for this project. BIM would be interesting at a future date, but is not a requirement for this project. I would like to start with a few simple drawings - the freelancer can suggest the starting quantity and amount per drawing. These starting drawings would be of (for example) A window sill, 6" wide x 4" thick x 48" long. the sill tapers from the back (4") to the front (3") A similar sill with an "end dam" on each end - this is a minor detail of a "brick-like" flat spot - I will send you details A piece of pipe - 12" inside diameter x 16" outside diameter x 18" tall with tongue and groove ends (google it) a square planter - 24"x24"x24" tall with 2-1/2" thick walls and bottom All of these would require plan, elevation and sections and reinforcing details, plus weights and possible finish details (sandblast, plain, exposed aggregate - which we would supply in a list for each) In total, there will be 100 or more drawings. Many will be similar - window sills and wall coping are all very similar and can be duplicated with minor changes (example - the 6" sill above may also be available in 4" wide or in 8" wide with 5" thickness or 54" long, etc) After the simple items, we will require picnic tables, benches, round planter bowls, garbage cans with plastic lids, bollards etc. prices for these drawings will be different and secondary projects can be set up once pricing is determined. I have included images of products and drawings that are very similar to what we are looking for. I would like pricing on the 3 types of drawings: simple sill or wall coping; slightly more detailed drawing like the pipe drawing; picnic tables
