Need help assembling a greenhouse and base setup in garden

I’m looking for a careful and experienced gardener to assemble a small greenhouse and install the base frame in my back garden. The kit includes a modular frame, polycarbonate panels, and a simple door. I’d like the setup to be level, secure, and weatherproof, with proper anchoring. Ideally someone who has done greenhouse assemblies before and can advise on placement for sun exposure. Tools should be brought by the worker, and I’m hoping to complete the project in one day. Please let me know any extra materials you might recommend (pavers, sealant, or anchors) and whether you’re available on a weekday morning.
